Review (5/5): I LOVE IT, A JOY TO USE!
**EDIT** 10/25/17
I've had this little beauty for almost two years (March) and it's held up admirably. I use it quite frequently so it's never really put away and always in easy reach. I did have to replace the hand piece at one point, but didn't have an issue with the seller in getting it replaced. I still give it 5 stars and recommend the unit to anyone.
This little machine is just amazing! It's so quiet you can't tell that it's on until you touch it to your nail. There's no vibration in either the hand tool or the unit. There is the option to control the speed by hand or a foot pedal. For myself, in a non professional manner, I'll stick to controlling the speed by hand. So I'll have no information regarding the foot pedal.
Controlling speed by hand is really easy. The bar you move to the right, to increase the speed, or left, to decrease it, gives you better control than the defined/set speeds (e.g. low/med/high).
The hand tool is a bit heavy feeling, but that's most likely due to the metal casing and most of the interior parts. This is not enough weight to interfere with its use. The chuck is easy to operate and it's simple to change drill bits as desired. The cord is a nice length and gives you decent room to work in.
The accessories that came with this unit are quite nice. I won't need to buy sanders for a looong time. You get three bags with about 100 sanders in each bag and each bag being a different grit. There are extra drill bits and it's a nice selection of bits in different shapes and sizes. There's no guide to tell you which bit to use for what, so it's trial and error and what your preference is.
I like the way the hand tool connects to the unit, by way of a 5-pin connecter. I had one unit where it was connected via a 2-pin connection. This shorted out and my husband had to hard wire it to the machine.
There were basic instructions for operating the machine. But again, nothing for the bits. I've just been experimenting with them, see how they work and which ones I like.
So aside from that little annoyance, I love this little machine, it's a joy to use. I've had a couple of different machines in the past and they didn't last long.
I have high hopes for this unit. The solid construction and materials it's made from are far superior than most other units out there (within this price range). I highly recommend this unit and would buy it again should the need ever arise.
Edit: I ended up having a small problem with mine. I contacted the seller who was quick to respond and resolve the issue. I'd buy from these guys again, 5+ stars!
