This Bonza Pro Mech was ThunderCloud’s first mechanical device, following their three atomizers. The build quality is perhaps even higher, with an excellent steel finish and top-level threading. In the package, there are several accessories to customize the Bonza Pro Mech, such as three cosmetic rings to match any atomizer, as well as an 18650 adapter so you can use those in addition to 21700 batteries. In a market where everything has become identical, ThunderCloud is the only brand that truly thinks of all types of vapers.

An awesome Mech mod
Voici une traduction fluide et naturelle en anglais, idéale pour un avis produit (type matériel de vape/mod) :
Honestly, the overall impression is excellent. The finish is simply superb: the engravings are beautiful and ultra-neat, and the threads are remarkably clean. You can immediately feel the quality of the materials and the attention to detail as soon as you hold it in your hand.
In daily use, it’s a pure pleasure. What I particularly appreciate is its adaptability: thanks to the different rings provided (25, 28, and 30 mm), you get a perfectly flush fit with whichever atomizer you mount on top. It’s really ideal for tweaking your setup to your liking without ruining the look of the mod.
When it comes to responsiveness, the switch responds flawlessly with a crisp, immediate hit. Big favorite as well for the rotary lock system: it’s simple, extremely clever, and super convenient for locking the mod hassle-free before slipping it into your pocket. A true success!

mech of the year!!!
outstanding device , great build quality and hard hitting.
here is my YouTube review :
The machining precision is excellent, making this a very high-quality mod.
By swapping out the beauty ring, you can attach atomizers up to 30mm in diameter without any awkwardness.
I own the stainless steel (SS) version; brass is used for the contacts, switch, and terminals, ensuring good conductivity.
I also really like the design.

My Review
A few things that stood out to me:
Switch: The firing bar seems to have a really nice feel to it—not too light and not too stiff. It looks like it strikes a good balance compared to a lot of other mech mods.
Weight: It comes in at 252g with a battery installed, so it’s definitely on the heavy side. Heavy enough to “pull your pants down” if you stick it in your pocket!
Build Quality: I honestly struggled to find many negatives. It looks like a very well-made device, and I think the collaboration between Sam (The Vaping Bogan) and ThunderCloud has turned out really well.
Customization & Price: I like that there are several emblem options to choose from. The limited edition is more expensive, but the standard versions seem reasonably priced.
Overall: From what I’ve seen, I’d happily recommend it. If you’re interested in the finer details, it’s also worth watching Sam’s own video, where he goes into the nickel coating and the design process in more depth.
