MAD Heaters Reviews 

Amazing communication from the company, very helpful and assisted me the best they could.

Went for a factory second then regretted it as I was worried about defects, item came 2-3 days later and how amazed was i!

You honestly couldn’t tell it was a factory second!
Cool’s the Vapor down by a mile, I’ll be looking forward to picking up the attachment for the mighty, this device really kicks ass and is probably the most affordable and most engineered product I’ve come across for the dynavap.

Why spend more when you can spend less for more functions.

Madheaters has some of the most exceptional customer service I have experienced in this industry. There were several growing pain type issues experienced with the preorder, and each issue was resolved promptly, painlessly, and professionally. Including having sent a full replacement after having receiced one of the problem units, which had excess black coating coming off while cleaning with isopropyl alcohol.

Beyond the stellar service, the Revolve stem is an engineering marvel. It's tolerances are industrially tight, and it's design and function are second to none. If I had any criticism at all, I'd request future iterations be manufactured 1/8" thicker ti throughout the body, as continued use (3 or 4 bowls) can make this stem wickedly hot to the touch. Outside of that, it is easily the most advanced stem design that one can buy right now, and I highly recommend it.

Love. These. Products! And the service is great too, very helpful and friendly. Best DynaVap kit in the game by a country mile.

Great service and fantastic products, very happy

Great team and great product !! :)

Honestly, this is a perfect product/accessory. I’ve been looking for over two years for a good container to go with my Dynavap (at home AND travel) and found nothing that suited my needs. I don’t know how else to say it but this is literally perfect. The fact that you can even customize how many containers you bring is just a cherry on top.

You guys better get this product out there to be seen!

This thing right here might be the smoothest hard hitting device i always want bets stem by far. The only thing I have to say negative is i found some metal sliver on the helicol coil but other then that i love it

Amazing stem.amazing customer service
Will definitely be using them again.

Just received my revolve stem and reload today.
It's so good. A huge difference in temperature of the vapor from my 2018 omnivap.

The reload is very practical as well. I will defo be using it all the time.

Both very well built and the packaging is very high quality for a stem.

Hurry up with the sense IH. Given the quality of these pieces of kit, gives a lot of faith for the quality of the sense 👍

MAD Heaters has some of the best customer service I've experienced with any company. They walked me through the payment process and were very patient with issues I encountered.

I can't wait to do business with MAD Heaters again in the future.

Im more than satisfied. They doesn't do their best only in the quality of their products, also in customer care! one of the best purchase experiences I've ever had!

Best products of its kind on the market. Excellent communication, a pleasure to deal with!

Provided a great discount for preorder and products look amazing. Can't wait to receive revolve and reload
