Great tension tool!
This is a top quality tension tool. Easy to use, just follow the directions. Not cheap but very accurate. You get what you pay for.

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

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.

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.

I'm a car mechanic. It's kind of a large tool to fit in some cramped engine bays. 95% of the time I seem to be able to get it hooked on to the belt so I can take an accurate measurement. For the vehicles that I can't measure, this tool keeps my hand calibrated which has stopped me from getting belt tension too loose, which was my former tendency. It's a well built tool that gets used every other day around here.

Very well made. Accepts thick serpentine belts.
Great tool perfectly sets tension. Far better than thumb pressure and a ruler. One reviewer says it only opens to 1/16 inch. Not true. There is a lot of spring tension in this device. You have to give the tool a firm squeeze to get it to open it up. Too bad the reviewer wasn't strong enough to use this tool. Very well made. Takes only a second to use. Have used hundreds of times over past 5 years.

Cheap plastic holding the spring breaks easily
For this kind of money, it is a solid tool except for the cap holding the spring in place, It is the kind of cheap plastic used in toys at the dollar store, self disintegrated in storage from the spring tension on it. They could have used Nylon, or thermoset, instead of few cents worth of junk plastic that renders a $200 tool inoperable. What happen to PRIDE? maybe somebody can tell me how to get a replacement?
