So far it's a great die grinder, for a decent price. Like a lot of the other reviews here, it did not come with the tiedye logo. I know it's just cosmetic but it was a selling piece for me. Hope they update the photo.

Love this little guy. Well made all metal item. Good lever for speed control and comes with an air hose connector for automotive shop use. We use T fittings here at our location so we had to use our own fitting. The rest is rather simple...

I had to tighten the nut at the top after about the first 5 minutes of use and oiling but after that smooth as butter with lots of power just as good as a Snap-On or Mac at half the price it does tend to get cold because it's all metal but will be a blessing in the summer and reminds me to wear gloves when working

When held on for more than 1 min it gets cold. Due to the metallic body instead of the composite body.

Amazing Die grinder compared to the low end HF I have. Very stable and does not vibrate when on. Much better than my low end HF Die Grinders.

Online is says it’s rated for 20,000 free speed but when I read the paper work it’s rated for 18,000, So which is it? Didn’t get the tie dye logo and I bent the stamped steel wrench they give you in the box. Maybe I should have spent the extra money on a ingersol rand instead.

Grinder works well but I wanted the tie dye logo and what came was just a generic silver logo and looks much cheaper

I use this for aviation sheet metal work, it's never let me down. You can pay more but this is all I have needed for about a year. I took the trigger safety off and lube it about once a month, no problems.
