Review on STYDDI Brass Garden Hose Repair Kit With Clamps - Male And Female Hose Connectors For 5/8" And 3/4" Rubber Hoses - 4 Piece Set by Darren Cole

I got both the 1/2" and the 5/8-3/4 parts. The half inch ones measure at 0.51" so should work great for that. But the others measure at 0.71" which is too big for my 5/8" hose and couldn't fit. They are also probably too small for a 3/4" hose and would leak. I suspect these are made to some metric size and they hoped they could sell them into the US market without making something correctly.I'll also mention that the many edges on these parts are quite sharp and can slice your fingers, so careful when handling. They really should be buffed out.
