Find someone else, better quality somewhere else

Cheap wiring, a few have already died which is a big pain when integrating into a project. Received a second batch to try again and same problems.

Pros
  • Handsfree
Cons
  • I won't say anything

It will work. for voltage tester

Not as bright as hoped, but serves its purpose. Seems accurate enough. The connection of the wires is very weak, it is recommended to apply a little epoxy so that they do not break.

Pros
  • Very good price-performance ratio
Cons
  • -

burned out for the first time

burned out very quickly at the first contact with the 28V power supply. Four out of six are already dead. But the remaining two (red ones) worked fine and looked good with a slight imprecision and I needed the size. Unfortunately I didn't get to install it.

Pros
  • good thing
Cons
  • I don't remember, but there something

Not impressed Good for testers

Two main problems: - the cable connections are COMPLETELY weak - they would break off very easily - the description is written with an accuracy of 3%. The ones I tested were hardly in that range, I mean hardly. They were cheap and I bought them as a test. I got what I paid for. If you're very careful with installation they will probably do the job, but I probably won't buy them again.

Pros
  • Doping 🔥
Cons
  • Expensive

Operates on 70 volts DC but will

Operates on 70 volts DC but will burn if there is no current limit from the b+ power input cable. Guess how I know this, yes I also plugged in my 70 volt battery from my electric scooter all night and in the morning it was dead. Repeated this at a test voltage of 12 volts and they work fine. 70 volts is my maximum DC voltage, so I tested at that voltage. I also compared them to the voltages on my Fluke meter and they differ by only 0.1 volts. Very simple, a black ground wire, a red B+ wire and…

Pros
  • Enjoyable
Cons
  • Legacy model
