## Customer Reviews

### ⭐⭐⭐⭐⭐ I Love It!
*by J***. on May 28, 2023*

I'm building an experimental airplane so I'm drilling a LOT of holes. This drill is light and compact. It has a two speed trigger and a large reverse switch. The switch is a bit in the way if you're left handed, but it is still a great drill so far. I know it's inexpensive and some may say that it lacks torque, but if you're stepping up bits properly you don't need wrist snapping torque. This is a great little drill.

### ⭐⭐⭐⭐⭐ Same as the Mac
*by A***H on November 19, 2021*

Got one a couple weeks ago, I originally ordered the composite reversible one and then the smaller aluminum one so now I have both. After comparing them with some of the drills other people have around the hangar it turns out these are the exact same as the Mac pneumatic drills. The aluminum one is the old style Mac drill and the composite is the new style Mac drill. Just for a lot less money. Very happy with them so far.

### ⭐⭐⭐⭐ Very good product for the price
*by A***R on October 24, 2022*

I like that it is very light and small. Seems to be made very well and pretty quiet too. I use it or aircraft structural and sheetmetal repairs. Only thing I don't like is the trigger is a little stiff and it's a 2 stage trigger, 2 speeds. That's the only reason I didn't give it a 5 star. We will see how long it lasts. Other than that a great deal for 40bucks!!
