"Masterpiece"

Without any doubt the best aftermarket accessory product for dynavap. I've owned almost all stems available on the market claiming to do miracles, bought MH revolve in preorder just after I had saw the presentation.. this is a top notch, the graal of stems. Being made of titanium this will survive to zombie apocalypse too, at a reasonable price deliver a vapor quality never experienced before giving to dynavap a totally new dimension.
Fully customizable, you'll have so many options to choose for that for the first two week you'll be blown off by tweaking and setting it just to experience all the configurations.
Last but.not.least, customer care is excellent fast and super available.

Once I understood my preferite setting now I'm able to draw a full bowl with two hits almost without playing with airport..incredible!
And if I want a fresher draw, just open the airport and enjoy it!

I really hope to see some new product from MH in next month to come..I'm already saving moneys for these!
Keep working guys!

"Possibly the best Dynavap accessory."

The revolve stem is amazing at cooling. I hardly want to use any other stems since purchasing. Everything seems very well planned and manufactured. I purchased a factory second version and was extremely pleased by the quality.

"Must haves for the serious Dynavap collector"

I’m so happy to have been following along with Mad Heaters since I first learned about them on FC. I own two Revolve stems and two reloads. I consider the Revolve to be a top tier stem in my Dynavap collection and the Reload is a must have accessory for the Dynavap enthusiast.

"Unfaultable"

Offers a better product than the competition for a better price. Bonus that I get to support a UK company. My glass tube cracked, I emailed him about it and promptly forgot, only remembered after I bought a revolve on 419 so missed my chance to get a free replacement included and he sent one separately anyway. 10/10

"Pick this up ASAP"

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.

"Fantastic Service & Top Tier Products"

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.

"Great products, great service"

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"

Great service and fantastic products, very happy

"Great team and great product !"

Great team and great product !! :)

"Amazingly perfect!"

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!
