Delta labs crush the experience. Real thca and pure you cannot find better thca in europe for sure. Fast delivery and amazing support. Their products works amazing and you will like it for sure. Good job delta labs
The hash rosin did not meet my expectations. I was expecting freshly pressed live rosin. The vendor refunded half of it in a coupon. The flower is medium quality and is not really pleasant to vape. I will admit it is strong though so smoking it might be nicer. The gummies did not really work for me but could be my tolerance.
***FINAL UPDATE***
This could have been a simple “sorry for the response delay, it was inexcusable, I have processed your refund” in which case, I would have removed the review.
Instead, this company sent me screenshots of my emails in the spam box. They must not’ve realised when telling me that it is only me with this issue that they showed me another email that is stating to be waiting for a reply. Also, a GDPR issue showing emails/names without consent?
This company have tried to claim to Trustpilot that my review was for another domain (a common tactic to get a review removed) Though, they have since retracted that.
This company had tried to place blame on me even though I was told in the Order confirmation to contact them on their email. The company’s claims that email is not for support were false until they changed the wording on the website. From my proof, this was after my review, but they deny this of course.
I followed their own written instructions, yet was ignored for weeks and then blamed for not using WhatsApp instead. It’s insulting.
If you specifically state to contact via email on the order confirmation email, there is no reason to assume that anyone would need to make contact via a different platform.
While they claim I should have used WhatsApp, a customer has every legal right to use email for formal records, especially regarding a breach of contract. They since realised this.
I will not be bullied into feeling like I did the wrong thing for using a standard communication channel that this company ignored for weeks.
Under UK consumer law (which applies since they are offering shipping to UK), a business cannot dictate that you must use a third-party social media app like WhatsApp to exercise your legal rights (i.e cancelling an order after over 30 days of non-deliverance).
Any decent business should know the consumer right of the countries that they ship to and allow payment from.
The company are complaining that it took 4 hours to find my order. That is an admission of internal incompetence, not a fault on my part. A professional business should be able to find an order in 30 seconds.
They have since retracted this.
The company was a lot more polite and honest over email than they had been responding to this trustpilot review, admitting that they understand they were in the wrong. But that quickly changed. Since emailing them to let them know of their unprofessional behaviour on trustpilot, their emails became very hostile and personal.
In my experience, it is clear that while they provide service to those who use WhatsApp, a customer who uses email and expects basic professional standards and honestly will be met with insult. “Huge loss of time” was the initial. Upon email, a “weak individual”. I have the full email chain as evidence of this, it is with Trustpilot directly.
Hence their attempt to remove my review for defamation failed.
They have since changed their reply to a more rational one, after an outburst of accusations, and threatening with court proceedings if I don’t change the review within 5 days. This also sits with trustpilot.
To anyone ordering, make sure you follow their website, and not what they tell you on your order confirmation or otherwise this is how they may treat you!
I had never dealt with such an unprofessional company before. 0 stars.
**original review**
I placed an order on February 17th which reached a UK hub on February 20th and has not moved since (not a customs issue). While I understand logistics issues can happen, the reason for my 1* review is the customer service has been non-existent.
I emailed on March 7th and then finally on March 19th (citing my legal rights to cancel after 30 days of non-delivery) and received no response at all, despite their website promising a 24-hour working day response time. Because my attempts to resolve this directly were ignored for over two weeks, I have had to recover my funds through a bank dispute. Extremely disappointed in the lack of professionalism.
**update**
Thank you for the response. To clarify the facts for other customers: The order was placed on February 17th. My first follow-up email was sent on March 7th, and my cancellation notice was sent on March 19th after 30 days of non-delivery.
The bank dispute was raised last night (after promising you 48 final hours to resolve).
While I acknowledge your apology regarding the 'spam' folder, it is disappointing that it took a public review to trigger a response after two weeks of silence. You are now claiming my review to be inaccurate, elaborate for me what is inaccurate in my review? I have noted your refund confirmation. For now, the rating remains due to the poor communication, lies and the necessity of public escalation to resolve a basic situation.

Hello,
Following the latest update to this review, we need to formally clarify several factual points that we dispute.
We also note that some of the statements made in the different versions of this review appear inconsistent or based on assumptions rather than on the full context of the exchange.
For this reason, we believe it is important to focus strictly on verifiable facts.
This review was not reported because of its rating, but because it contains statements presented as fact which do not accurately reflect the underlying exchange.
First, no insulting or abusive language was directed at you in our initial handling of this matter. We retain the full communication record.
Second, the screenshots referenced do not establish that other customers were “waiting for replies for extended periods.” They showed standard spam-folder content and isolated messages, not evidence of a broader unresolved support issue.
Third, we did not dispute your right to contact us by email. The issue was the delay caused by misclassification of prior emails, which we acknowledged and for which we apologised. Once your case was clearly identified, your refund was processed.
Fourth, the claim that our support instructions were changed following this situation is incorrect. The wording referenced had already been updated prior to this order.
Any suggestion that changes were made as a result of this review or interaction is therefore inaccurate.
We acknowledge that the initial response delay did not meet our usual standards. However, we do not accept the inaccurate characterisations and factual inferences that have since been added to this review.
Our position remains simple: customers are fully entitled to leave negative feedback, but factual claims should remain accurate.
Best regards,
Victor Delloye — Delta-Lab
Fast delivery and very good product
Ordered from here recently and everything went great. Discreet packaging and the delivery was pretty quick. The buds smell amazing and the quality is honestly really good. Very satisfied with the whole experience.

Im giving it 2 starts just because they gave a bit of freebies and the product where what they where described as but when it came to measuring the products almost all of them came short with 0.2-0.3grams missing ( i ordered in small quantity 2grams per pack) and instead of receiving 2grams of hash i got 1.6grams, i sent 3 emails already asking for compensation of some sort or atleast a discount but they refused to answer it. The high was actually somewhere about nice but the costumer service is really bad.
Reply from Delta-Lab
Hello,
Thank you for your feedback.
We take product weight very seriously. Every product is weighed twice during preparation before shipping. While minor variations can theoretically occur, a consistent shortage of 0.2–0.3g across several packs would be extremely unusual. In fact, you are the only customer who has ever reported such an issue.
As you mentioned, we also included several free samples in your order as a goodwill gesture.
Regarding customer support: as clearly stated multiple times on our website, customer service is handled through WhatsApp for fast assistance. This information appears on the header, checkout page and support section. Email is not our support channel, which is why customers are advised to contact WhatsApp if they want a quick response.
For accuracy: we received two emails from you within a 72-hour period, not three, and they only contained statements about missing weight without any photo or video evidence. It is also written on website that we aim to reply to everybody in 24 hours, but letting us only 72 hours to resolve an echew and reply to you is short delay.
If you still believe there was an issue, you are welcome to contact us on WhatsApp and provide photos or a video showing the weighing so we can properly investigate the situation.
We always aim to provide accurate products and transparent customer service.
Edit after reviewing the order:
After checking the order details, we noticed that no 2g packs were purchased. The order only contained 1g hash items. The only 2g product in the package was a free Candy Runtz static sample that we included as a gift.
So the weight concern mentioned in this review appears to refer to a complimentary product that was not purchased.
To clarify: free samples are provided as a courtesy and are not part of the paid order. Requesting compensation for a free item is therefore difficult to understand.
As mentioned previously, if there is a genuine concern about weight, we are always open to reviewing clear photo or video evidence through our WhatsApp support channel.
Best regards,
Victor Delloye — Delta-Lab 🧪

I gotta Tell you, if you want good flower or Vapes (the real deal), for cold-Infusions ofc 😅, Delta Lab is THE SHOP, Vapes Are more than reasonable priced (the NL Stuff costs Like x2 and you Most of the time get some disty, which doesn‘t Even come close to what you get from Delta Lab)
The Purple Gas Rosin Vape tastes Like Heaven and Effects Heavy Indica, i love it.
The Super Lemon Haze tastes like hitting my dry herb Vaporizer with some Fire Lemon 🐰, also love that one Yessir Yessir.
So if u want the real deal and also Safe Vapes Go with Delta Lab
With that Said I Hope everyone Reading this has a beatiful and lifted day 🙌💚.
