    That's it light and easy to use
  

*by S***A on Reviewed in the United States on February 9, 2020*

Light weight and very smooth pencil grinder

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Works better than expected - lost a star for unreadable instructions
  

*by L***S on Reviewed in the United States on May 23, 2018*

I did not give this 5 stars because the instructions are in a foreign language I can not read. That said, there are good instructions on YouTube to answer your questions. Also, it does not say what PSI is max. Others like it that run 70,000rpm use a PSI up to 90. I am using it on wood and find that 60 - 80 works just fine so I have not even tried up to 90PSI.The fitting that comes with it does not fit my air supply but we had extra parts laying around so it was not a big deal for us - but you need to know and most of the cheap ones will not come with the right fittings. It also does not come with an air regulator. You can buy one for in line or set the one on your compressor - but you do need one.Due to shipping restraints they could not include the bottle of oil and there are no instructions in English that tell you how. Try YouTube. My guess is most of these work the same.It comes with two colettes. I needed one that was even smaller so I used one from my Dremel and it worked. For fine stuff I use 1/16 and it does not come with that.Before changing bits be sure to cut off the air supply at the hose and not the handpiece. Be sure you are holding the pen when you turn the air on.Now for my performance review - I will be honest, I did not expect much from this and I was pleasantly surprised. It is awesome. Since I got it yesterday and just played with it for a while last night at the power carving meeting, I have no idea about it's longevity but I think if you are careful with it and don't use too much PSI it should last a while. Keep it oiled (again, no idea how often to oil it)Over all, I think it was a good purchase. My friends liked it and plan to get one too. After I have had a chance to get into it more if I need to I will update my review but for now I like it

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Works great with a little tweek
  

*by A***A on Reviewed in the United States on October 7, 2019*

For the price it works amazing unfortunately it comes with a hose adapter it doesn't fit anything from Home Depot or Lowe's hardware so I had to make my own fortunately enough I'm good like that! Surely there is always a simpler solution but I enjoy the challenge of solving the problem myself. Or I'm cheap u pick
