CO2 Supermarket Reviews 

Great product and web site is super helpful with advice.

Brilliant, honestly just brilliant. I wasn’t sure in what to do, how certain parts worked and I was a literal pain in the hoop for Martin who professionally reassured me on every engagement. I now have 3 tanks running with the pro dual regulator setup and it’s been flawless.

Fantastic customer service

I bought the Pro Co2 dual stage regulator and found the instructions great. I had a question about it and got a reply in a few hours which was incredible. I can't recommend this company and their products highly enough.

1FB-U7EXWLB fantastic service and very helpful advice. The regulator I purchased feels like high quality and was very easy to set up and is working very well.

Nice quality item. Happy with service. Works well so far and happy with the purchase. I did speak with support team after small problem (mainly my misunderstanding) this was resolved swiftly and curiously. Thumbs up from me

I have used this company several times and have asked for advice on multiple occasions. The items I have received have been top quality and the customer service advice has been incredible. Often responding within hours on a Sunday. I would highly recommend this company.

PTFE gaskets arrived on time via 2nd class postage and quality of fit is up to quality expected.

Helpful company with good advice and recommendations. No quibble refund on item I purchased in error. Highly recommended for your CO2 requirements.

V prompt reply to my enquiry and provide links to the components I needed. Having ordered the parts they arrived in a couple of days. 👍

I don’t go anywhere else for my co2 needs. Best equipment at the best price. Never had an issue.

Always fantastic service, Martin is always at hand to give advice & information when needed with prompt replies on Behalf of Matt S

God quality kit, clearly described, and fast delivery

I was well looked after, and the item arrived promptly. What a unit! the thing is absolutely awesome. Revolutionise my system. Thanks

I ordered the SodaStream Quick-Connect Cylinder Refilling Adapter after consulting the CO2 Supermarket website, which has lots of useful information. The adapter arrived swiftly and works very well. It isn’t cheap but well-made and I wouldn’t be confident using any of the cheaper options advertised on Amazon or eBay.

Having already purchased a full co2 system from this company which has impressed me in both quality and functionality I went back to them to upgrade to an atomiser. Unfortunately the atomiser leaked when installed i contacted Martin who was incredibly helpful and replaced the faulty part without question fantastic service will definitely use this company again.

Co2 regulator.
Product was ordered on the Sunday and was received on the Tuesday. Excellent service. Received an email on the Monday with links to the Company’s website to instructions how to set it all up. Again this was appreciated.
Product itself was of a very good quality and looks very professional.
Had a minor problem in that the diffuser would not work, the co2 kept blowing out of where tubing connected to it and nothing out of the diffuser itself.
A search online suggested this was not uncommon and to just leave the diffuser to soak overnight in the tank and next morning all was good.
Perhaps this should be added to the instructions for the diffuser to prevent this happening to other people.
All in all I highly recommend this product.

I wouldn't normally give feedback like this as I appreciate issues can occur and that resolving such things can require time or a process to work through.

In this case I have decided to do so after an exchange over the last couple of days. I ordered a co2 regulator with solenoid a while ago, and after only a couple of weeks of use, the solenoid has stopped functioning. As a result I have had to micromanage and adjust things to ensure the safety of the animals in my aquarium. I have previous experience with solenoids and was able to try and troubleshoot myself to no avail with some less than ideal tools.

I got in touch and was prompted to do some things that I had already tried, and when I informed the customer service rep that I had done so they arranged for a new piston to be sent. I personally think that a replacement piece of equipment would provide a better experience but that isn't really an issue for me beyond the specific need for me to grab a new wrench to perform the replacement.

A relatively short while later the part arrived. Due to a mixup with the size of the tool I ordered and some other things going on I wasn't able to switch this straight away, but on doing so a couple of weeks later I discovered that the issue was not resolved, so I got back in touch to register my disappointment and move forward with fixing the issue.

The response from the rep was quite rude noting that I hadn't responded for a few weeks. I responded to give a little context as to why, and their reply was questioning why I needed to get more equipment to perform the fix they had provided.

I don't see how that is relevant to the issue at hand. I have paid for a product, the product has failed within a few weeks and that in itself is something I would hope is resolved apologetically. The cause of delays to my attempts to fix this are hardly a reason to continue pushing back, especially in the confrontational way the exchange has gone. I just don't want to continue wasting CO2 and having to micromanage a system that I have charged their product with automating.

The next solution appears to be that I will need to return the faulty valve so they can send a replacement, for further time without a functional product that I have paid for. However, I can't confirm whether I will have to go for a few days without a valve as the chat has been closed down while the team are away for a few days.

I don't expect employees or businesses to be always on, but the lack of urgency in resolving this is getting to be very frustrating now. I do accept that part of that was due to things that I had control over, but in my opinion a more proactive process to fix this would have been appreciated if the team were aware they were going to be unavailable. The approach has been very disappointing.

My past dealings with CO2 Supermarket have been fine so I didn't want to score one star, but the final exchanges over this problem have really knocked my confidence in using them moving forward.
