It's small, it's lightweight, it's has advanced controls like Bypass and Temp. Control, and an internal USB-C-rechargeable battery for ease of use. It also has 2 other great features: 1) a raised ring inside the boro to prevent any leaking juice to create a suction against the inside and 2) an adjustable boro pin for better fit from tank to tank.
The Temp. Control works as well as any other mod I've tried, which is to say, just okay. There's no warning for over-temp and the power will just cut out on you or pulse on and off as the safety cutoff turns on and off. Then you just have to adjust your temp or starting power and try again. No biggie.
One downside, and the reason it's 4 stars and not 5, is that you can only use the integrated drip tip flush nut that comes with the mod. The mod doesn't accept other industry-standard flush nuts or integrated tips to be threaded into it. Strangely enough though, the integrated tip that comes with the mod will work in other boro mods; just not the other way around. You can however, switch out the 510 mouthpiece itself for whatever you like as long as you use the mod's own flush nut.
