Other reviews seemed confusing or contradicting so I'll lay out the facts and what I observed with this gun (the 3/8 drive 15 max). First off yes, unfortunately the gun is made in China unlike most IR products, but the quality, construction and feel of the gun is comparable to my other USA made IR tools. The gun I received does not leak whatsoever, so if yours does just send it back to amazon and get a new one; it's defective.. For my test I use a 3/8" x 50' rubber airline with no leaks, and 1/4" NPT V-type air fittings. 3hp 30 gal compressor running 100 psi in the line. Oiled the gun with standard air tool oil as soon as I took it out of the box. I used a torque wrench to tighten the lug nuts on my truck to see what the limit of breakaway torque this gun will make. The lug nuts are 9/16" -18 clean, rust free, dry threads and 3/4" hex nuts. Using a deep impact 3/8" drive 3/4" socket and no extension I found that the limit of this gun is between 154 and 158 ft lbs of breakaway torque on that specific size of lug nut. I tried multiple times and multiple nuts, and it consistently would not loosen bolts torqued to 160 lb ft and would always loosen torqued to 150 lb ft. 155 lb ft is 50/50. When tightening the lugs until the gun completely stopped turning the nuts came out to between 120-130 ft lbs tight. You might think that's not even close to the advertised torque, but the manufacturer torque ratings are always some made up number in a specific test to make the gun perform as best as possible, with no real standard. Either way, that's more than enough torque for most real world applications like brake, suspension and under the hood work. This should not be your main gun by any means, but it is a specialty tool for tight spaces and does exceptionally well at that. It's also very cheap for an IR tool... Only ~$30 more than the harbor freight earthquake? Maybe I'm biased to the brand, but it seems like a no brainier to me. Earthquake might last 10 years, IR will outlive you.
