"Even better than the G1. Love it."

I have had my Revolve G2 over a week now and I am loving it as much as I did on the first day. I like my G1 a lot as well, but the G2 is MUCH cooler to hit and even more adjustable. The new filter system is much better and easier to remove and replace. And the mirrored finish on my Rainbow G2 makes the color really pop like it's lit up. Absolutely beautiful.

"Amazing quality stems and good service"

I've always used the vong with a water piece, without it was too hot. But when I use the revolve just on it's own it pretty much cools just as well, no glass piece needed. Clearly this is the best cooling stem on the market, I always use it on bypass mode with the secondary cooling unit and it's fantastic. It gets hot really fast but not if you use the glass stem. It's a little pricy but worth every penny for me, it's the only stem I use now. I pre-ordered it and when I contacted the customer service about my order they were very helpful

"Mad Heaters online shop review, a great experience"

This is my personal opinion for the Mad Heaters online shop

Pros:
-smart UK design + good quality China made = fair prices and great products
-shipping is always well packaged
-customer service is on point
-IMO RevolveV2 and Reload are the best DynaV cooling stem and container to date
-custom official DV accessories available

Cons:
-order from the UK to Europe you could get some import fees
-only place to get all Mad Heater's products in one online shop.

The company owner is available, kind and care for is customers, check the FC forum.
MH products are "luxury" items, these makes the DV experience more refined, cooler and easier.

In a nutshell, the Revolve Gen2 stem give me the same cooling as a simple 14mm J-hook, but in compact form factor.
For me, Mad Heaters did the ultimate DynaV draw control and vapor conditioning stem.
If you purchase a Revolve, get a glass quartz sleeve for flavor and learning the device faster, and the Direct airflow tube in case you don't like the DRC air-path (and a 10mm non-frosted glass adapter, for glass piece lovers).

The Reload is a well-made Swiss army knife for DynaV. With it, you have in one compact product almost all the features you need for your Dyna session and maintenance.

Buy these products, if like me, you use DynaV as a daily driver or regularly, and can afford it, it's worth it.
If money is tight, it isn't worth your money now and cheaper options exist.
Finally, if you want to change your overall DV experience, and vapor cooling is not a priority, a good Induction Heater (MH Sense, not releases yet) should be a better upgrade than any DV stem, in my opinion.

"Awesome piece of craftsmanship and awesome customer service"

I got the revolve 2 as my first custom stem to my OG M21. I yet have to try ever option but I already see it as the only custom stem I ever need. You can use the super cooling open mode for very hot one-hit extractions (yet not so flavorful) or the flavor chasing direct tube for (less clouds though). I does everything it promised and it's fun to use! Definitely recommend it 🙂

"Revolve Gen2"

Absolutely love it! Top quality machining and materials. Such a joy to use. So many options and so smooth. Certainly the 'high end' of products in this category. The best in it's class! The customer service is faultless too. Extremely happy all round!

"This is the best stem with its cooling system"

This is the best stem with its cooling system.
it provides very smooth taste and also it is very simple to take a part to clean. Big cloud!!

"All top notch quality products"

All top notch quality products! There are occasional delays in email responses from customer service, but that isn't something that's a massive issue; in fact, this little issue aside, their customer service is impeccable.

"אכן מהפכה"

סטם מהפכני, שליטה פנומנלית בזרימת האוויר, המווסתת על ידי שני מצבי אב: "פה לריאות" ו"היישר לריאות". תוסיפו לזה 3 מצבים של האיירהול וקיבלתם 6 קונפיגורציות שונות. התוסף של הפילטר על הקונדנסר נחמד, מצד אחד צריך להחליף אותו כל יום יומיים, אך מצד שני צריך לנקות את הקונדסר לעיתים רחוקות. אפשר גם בלי. הפיה המסתובבת מסתובבת נהדר, טיפ טיפה חיכוך בשרוולים מזכוכית. ואם כבר מדברים על שרוולים מזכוכית הם הופכים את הסטם הזה לחוייה המושלמת לחובבי דיינא. וודאו שאתם מזמינים את הזכוכית ריינבו, היא ממש ממתק לעין.

"It Works!"

Madheaters is an excellent company, they treat their clients really well and they offer great products at even greater prices. If you go for the Revolve I'll assure you it's the last stem you are going to get, I usually use water pieces for my cooling needs, but with this stem I can go native without destroying my throat :)
The reload became a must have for outdoor sessions and it's packed with features! If you are on the fence about getting a product from this store, don't worry! The only problem you should have is choosing the color of your Revolve or Reload ;)

"Give them a try I am sure you wont be disappointed"

Most reviews are usually negative because most that are happy don't take the time to rate things. Its mostly the upset customers that take the time to write bad reviews so i wanted to take the time to give MAD Heaters some kudos.
I have had nothing but good things to say about MAD Heaters since I found them. This product is by far a 5 star product and then to top it off with some of the best customer service I have had in years, its a 5 all day long.
I received my medical card and did not want to combust, and didn't feel safe with everything added to vape juices. I tried edibles and found they did not work for me. I then ended up trying sublingual delivery with tinctures and hard candies. I found this to work ok, but the options were so limited that I just was not getting the results I needed.
So research led me to vaping dry flower. I started off with a Dynavap M, then an Omni, then an Omni XL. I tried a Mighty plus with and without water. All worked ok but i wanted something cooler and easier to use being i am an all evening medicator. I needed something simple and clean. I then found MAD Heaters.
I started off with the Revolve Gen1 and a Reload both in silver. I loved everything about both of them and the customer service was beyond expectations. the few issues I had were resolved above and beyond anything a person would expect.
I then tried the Revolve on my Mighty plus and found it cooler than any water I was using. So I wanted a second one for a daily driver so I could leave the first one with my mighty. I ordered a second Revolve in black along with a matching Reload that has been my daily driver for some time now.
The Revolve and Reload left very little for improvements and i was completely happy with my set up until i saw what was coming next.
The Sense was still in the works and i was so looking forward to getting away from butane. Due to whatever issues they were having and the constantly growing improvements they have been making to it during R&R before its release, its has fallen a bit behind on a release but i continued to follow MAD Heaters for a date.
Then i saw the Revolve Gen2 coming out. When you didn't think there was much if any room for improvement, they found ways of making it better. I have to have one.
So here I am on the edge of my seat typing this waiting for the Per-Order release to drop in the next day or two so i can order yet another Revolve. And yes i am still waiting on a Sense and any other things they have in the making.
Again i cannot say enough about these great products and the incredible customer service they have. Keep doing what you are doing. There are not many companies out there that have both a top notch products as well as great customer service.
Give them a try i am sure you wont be disappointed and if for some strange reason you are, i am sure they will make it right for you. So you don't have anything to loose.
Thanks for helping make my pain management manageable
