Items arrived and are as described, I haven't used it yet. I've bought several other brands and they stop working after a couple of months. I hope this one lasts longer.

I like AENG products and this one is pretty good too. Well made and hand size too. Will update when I actually test relays. Happy so far.

Arrived quickly and in working order. Cables are a bit short but can be daisy chained easily. In a quick test everything was as advertised and detects 12v battery on connect. Tested multiple relays and the test was quick and accurate.
