As a retiree and a hobbyist that enjoys car restoration projects this little sander has been a good addition to my shop tools, it is lite with both the PSA and the Hook & Loop pads also included a ( big plus ) and at a reasonable price this sander makes a good investment. I have not own it for long but for the short time that I've had it i must say that it has already been put through some heavy work, as of this time i have been very satisfied with the hand comfort and its performance. IMO this tool just like any other air tool i think that if you take care of it ( Keep it clean, oiled use the recommended air pressure ) and do not abuse it, you will get good reliable service out of it for quite some time.
