was unsure how this semi automatic version would work but as it happens it works really well ,just screw the nut rivet onto the selected size thread on the end of the riveter place in the hole and squeeze ,which is the hardest part as the larger rivets need a lot more strength ,i did find that it's easier if you dont open the tool fully for those , once you've set the threaded rivet just open and close the handles once or twice and it releases ,Great nice and simple thanks to a similar design to the old school ratchet screwdrivers you know the ones you push on to twist the screw .anyway it comes in a nice blow moulded case with a good variety of metric and imperial threads .

I got the assisted model. I can't imagine trying to unscrew in tight places without it. It takes some muscle to use but this tool is surprisingly well made. Definitely can't beat the price. I doubt it would run long if your using it everyday but for me putting threads in my jeep frame it's perfect. 5 stars

Not used yet but seen a youtube video and now I have it in my hands it is well made and well supplyed with nuts

Well made and works well. Needed stainless steel rev nuts for my application (not included with this package). The 16 inch handles were a MUST for the 3/8 in rev nuts of s.s. Any shorter handles and a someone stronger would be necessary ( I'm 78 and have lost strength). Have not used other rev nuts, but others should require less muscle?
