CEEYSEE 50Pcs Ring Wire Connectors M4 of Yellow Insulated Electrical Crimp Connectors Copper Ring Terminals（PRY4)

As described, great price

Perfect size holes for the power supplies as in the photos.I prefer crimped and soldered but it's confusing to guess the correct sizes from photos on Amazon.If you buy a box of different sizes, it's Sods Law (Dick's Law) there won't be enough of the size I need.Also 100 of the little blighters, so should last err........ forever..... almost.PS. Don't know why my photos always show upside down. (Just turn your phone round)

They are made from considerably thinner steel than similar M4 connectors I removed from a 1HP motor. Or even other M3 connectors I had. So it made me uneasy as to their current carrying capacity which is not stated on the packaging. As they are so thin, they appear to be more easily damaged / broken from the terminals. For that reason I would avoid and opt for a thicker connector or one that states their max current carrying capacity.

Really impressed with these eirth tags, very well made and strong much better then any I have used before, very high quality at a can't be beat price, I will definitely buy again and again, can't thank the supplier enough 5 stars 😀

They were just what I wanted for a small job

Excellent quality, far better than the quality you get in the multi size boxes

No issues

Work as expected, crimp well & don't feel loose as some do, would buy again if I need to

Buono

Acquistato per la 3ª volta, non mi ha mai deluso. Non li ho presi per uso elettrico, bensì come supporto per l'esposizione di fotografie in grande formato.Ottimo rapporto prezzo/qualità!

Troppo risparmio, sui materiali...Non li acquistero' più.
