Which Circuit Breaker Finder Should I Buy? Klein or VDIAGTOOL?

I’ve narrowed it down to two circuit breaker finder kits: Klein ET450 for home electrical work and VDIAGTOOL V500 Pro for cars. I only need one circuit breaker finder, but both are tempting.
Please help me pick the best circuit breaker finder!
