OTC Tools 3500-01A Mid-Range Amp Probe

This has treated me exactly as I expected it to. It takes a bit of fiddling with the fine tune to get it to read exactly zero when used with Fluke meter 88v. It arrived in the exact same package as another seller posted pictures of. It seems authentic, although OTC could go a bit farther out of their way to write a better manual to go with this item. I've had no issues with measurements. It seems solid. I love it and will buy another one if this one conks out.

I love this amp clamp does everything I need and it comes in the same packing as my picoscope champs as I think it’s made by the same company..I use it for relative compression testing. The signal is clear and crisp I use it with my picoscope and Snap On scope. The one thing I don’t really love is the short cord and that it’s coiled like a old phone cord so after it stretches it looks terrible and very hard to wrap up. Overall tho it’s a great buy.

I reasonably sure OTC has some sort of actual logo on their boxes. I seriously doubt the legitimacy of what I received. It's a hassle to return and reorder so I hope it works ok for a while.

If you work on cars OTC is a must very good probe

It worked as designed. My primary purpose for it is to measure starter draw current.
