My husband is extremely happy with this OTC Tester! He said it does everything it is supposed to do. It works very nice, it seems to be a very high quality, and it has already been an extremely helpful item for him! He was sad that it is made in China, but he said the quality seems to still be great for OTC. He does think that for the $100+ price, it should come in a case to keep it safe as it is a bit delicate to be loose in a toolbox drawer. I'll be looking online to see if I can find him something to put it in. Any ideas from the other buyers here?

Hooked ip to car as per instructions, 1 light lit up but wouldn't activate injector.Flimsy tool .

Worked perfectly right out of the box. I saw a YouTube video which demonstrated the use of this exact tool. The most difficult part of the job was accessing the fuel rail in the car. I would recommend this tool to anyone that wants to check the pulse of each fuel injector and therefore positively diagnose a bad fuel injector.

It worked well for me the first time I used it. The second time, it failed. I contacted OTC and they sent a free replacement. The warranty/replacement process was very "manual" (I had to call, exchange emails, follow up), but the tool was replaced within a reasonable timeframe.
