Paid for it's self in the first use!
Simple to use just plugs in to the hvac control board blade fuse holder and that's all.. comes with a 3amp and a 5amp mini breaker as well as 3 of each fuse.. saves you all the blown fuses when trying to diagnose a hvac system.

Troubleshoot Low Voltage 3A and 5A Circuits Without Wasting Fuses
This fuse saver worked better than expected. I had already blown a few fuses before seeing this in a video about HVAC repair. So, I bought it and yes, it works as it should. This kit is basically two circuit breakers, one is 3A, the other is 5A. They both have long leads which is plenty for being able to reset it away from the circuit board or fuse box you are working on. I used the 3A for troubleshooting my HVAC issue, and I was able to fix it without wasting any more 3A fuses. It came with a pack of 3 3A fuses and 3 5A fuses as well. Great kit!

Lifesaver!
I wasted 3 fuses trying to find a low voltage short in my AC system. The fusesavers allowed me to trip the fuse repeatedly until I found it! It even came with new fuses, so I could take it off and use it elsewhere. Plus it comes with a 3 and a 5 amp. Excellent purchase!

Works great. Would be nice if it had a slightly smaller form factor.
Works great, strong and hard to misplace.

Professional diagnostic tool.
Beats carrying around a pocket full of fuses. It’s a rather have it than not need it than need and not have with this. Lets you troubleshoot and be wrong until you figure it out. Press the reset and try again.
