Game changing experience

Great one. I’ve been using their products for a couple of years now. I started with the Dynamo and decided to treat myself for my birthday by getting their premium Tornado.

It's been a game-changing experience. I can even work out while traveling, so I don’t have to interrupt my progress.

Gripzilla tools best warmup for pickle ball players!

honestly didnt think grip strength mattered this much for pickleball but the dynamo and tornado are legit game changers. been using them to help with my hand speed at the kitchen line and the difference is crazy... my resets are way cleaner now and i can actually put some real heat on my drives without feeling like the paddle is gonna fly out of my hand. 10/10 worth it. my wrist finally feels solid and the paddle doesnt twist anymore when i catch a fast one off the edge. if ur struggling with dinking or just getting tired by the 3rd set just get these. definitely improved my game.

I've been using this tool for a few…

I've been using this tool for a few weeks now, and the results are noticeable — increased forearm size and definition, exactly what I was hoping for. It hits muscles that most exercises overlook, and the resistance feels smooth and effective. The build quality is excellent, and it feels like a premium piece of equipment.

The only downside is the excessive packaging — not the most environmentally friendly choice, which is something I hope they improve. Still, if you're serious about grip and forearm training, this tool works.

Tornado

The Tornado is one of the most amazing workout devices I have ever encountered. It has dramatically improved my grip and just my forearm size in general and, had consistently been one of my favorite workout devices that I have ever known. Just the increase in my grip strength has made me so happy! I would highly recommend the Tornado to anyone looking for bigger forearms and a better grip.

10/10!!!

I didn’t expect that this Tornado thing will really help to improve my wrist “situation”. But it did!
In a few words - I am a tennis player and I always had wrist injuries. Literally once in 3-4 months. But after I started to use Tornado i forgot about it! Thank you guys! I was thinking to change hobby but now I won’t😊

My shipment did not arrive

My shipment did not arrive. The tracking service showed the problem and the customer service was disengaged. I asked them to see what happened? if the order they sent me had arrived back but they ghosted me.

Horrible Customer Service

My product was incredibly delayed and whenever I attempted to contact them to follow-up or get a tracking number, I'd get an email back saying that the email I was writing didn't exist. It happened more than once and this is the email I was told to write according to their website. I'd then have to go through their support chat/email which would send me round and round to the email I first wrote. Then when I would get a response, they'd sent me to an unreadable website to track my order which made no sense. It all seemed very shady. I get my product very very late as mentioned and I was unhappy so I wished to return it but their return policy was 14 after order is placed even though I wait 6 or so weeks to get my order. So I attempt to reach out again to see what can be done and then I go through this process again where it's round and round and it all feels like a scam. So I unfortunately had to eat the cost and stick with the product as I was unable to return it. Horrible customer service and business practices. Avoid at all costs.

Never Received my order

My order was shipped on June 6th, and they still have not delivered my order. I paid about 70 dollars for shipping and they used the cheapest shipping method in the world to deliver my order. They keep telling me to contact DHL when I ask for a refund. I contacted DHL and they said they sent it to the post office instead of the shipping address, how is that my problem? There is no tracking of where my order is or how I should get it. Whenever I ask them for a refund, they tell me to contact DHL. This company is not legit, and I do not recommend buying anything from them.
