Well made
Works great for getting belts to the correct tension. It's very easy to use, just kind of bulky so it can be hard to get it in tight areas. You can leave it on the belt while adjusting the tightness, making it really easy to get it to the right tension. s

You need it as a Automotive Tech
When I first started, the Sears automotive tech technician instructor told us that we needed one of these. Well after five years of ignoring that great advice I finally bought one and realized that I have been a moron and I should’ve bought one five years ago.

Great tool but expensive and large
This is definitely the most accurate way to get the tension of an accessory belt. Compared to the Kriket style gauge, its no contest. I did back to back tests with this and the Kriket, and the Kriket was all over the place depending where you placed it on the belt and how far you depressed it. This had accurate precise readings every time. That being said, its hugely expensive and so large that I needed to remove the undertray of my car (a 45 minute process) in order to use it.

great tool that i would buy again!
i bought this to use on our coach based on the recommendation of a couple of professional mechanics.the first order was promptly delivered but based on what appeared to be a mfg defect, the plunger guide broke apart after the first couple of times that i depressed the plunger. i filed a return / replace with amazon / the vendor and the vendor responded immediately apologizing for the problem and said they would ship a replacement asap. the new unit arrived two days later.i used it yesterday on my coach belts and it worked just as expected on the belts i can easily get at. truth be told, i can't seem to access the serpentine belt as it's too close to engine block / various components so i'll have to (a) buy a different type of tension gauge or (b) solely rely on the new tensioner i'm installing to do its job.

Works great
Works great for setting belt tension on exercise equipment (treadmills, ellipticals, bikes, etc).

Too large for modern vehicles
The tool is reasonably well made, but it's simply bizarre that the gauge face is facing backwards. On very few vehicles can you slip this tool on from the back of the belt which is required with this tool. The tool is also very large so I'm lucky if I can even get it on a modern car.A better design would have been to turn the legs around opposite thier current orientation and extend them out an inch. That would work on may more cars.
