I've only used it once so I'm hoping it doesn't fail like another reviewer said but for now I'm giving it 5 stars. Changed coils from 13" 650# to 14" 700# on my Icon coilovers for my Tacoma. I've tried this before with 600# to 650# coils on a friend's car and standard rental compressors. We literally thought we were going to die. This type of compressor felt much more secure and I have never felt less secure. Spent about 2.5 hours including removing and installing tires. We spent almost half a day with two rented compressors and broke one before turning to a professional for another installation. Only use them once or twice a year, they're a good buy. I'll update if anything changes after repeated use, but so far so good.
