Review: This is the third drill I bought from this brand. I still have the first one, I sold the second one and I regretted. So I got this one and I'm happy with it. It has hi RPMs, doesn't makes my hand feel tired, good for small spaces. It is 1/4" so don't spect a high torque. It is realy good any way. It is identical as Mac Tools, but cheaper.

Love this little guy! So so light and convenient. I work on naval aircraft as a contractor and I’m obsessed with this thing. My coworker who is a “tool connoisseur“ says that the trigger isn’t 100% smooth, but I joked he just needs more control with his fingers. 🤣 I’m relatively new to air tools so maybe it’s a 8/10 or 9/10 but in my opinion it’s definitely 10/10. I’ve enjoyed showing it off and everyone definitely loves the size and lightness of it and a handful want to replace their air drill with this guy. I’ll update if it doesn’t keep up or burns out too easily.
