Excellent price. Great metal body. good density but I don't really care. I used a few of these and 2 other APP block styles from Chunzehui. I opened them all and find them well made. The connectors they come with aren't a real APP, but are sooo close that you really have to look closely to realize they're not. I have real APP connectors and they fit perfectly with these blocks. great, i added a set of wires to the one with the APP at the end so it connects to the chunzehui fuse box and i had all six connections available. I also added reverse polarity protection and just like with the loose wires I connected an LED (green is good 12v, red is 12v reversed). Doesn't take much and works great for auxiliary power (low power stuff) for discord on a radio shelf. Chunzehui, wants you to craft a protective box like WM does. They are very good but expensive. I would think Chunzehui can do this for half the price. Any radio operating on AC/DC power and/or a backup battery must have one. Overvoltage protection and undervoltage shutdown in one.
