Carabiner

When buying a carabiner always go for the best one, it can last you a lifetime. 
however if you happen to drop it on a hard surface, be sure to dispose of it 
and get a new one, even though you may think it looks fine, a small crack could occur invisible to the naked eye, and with some pressure the carabiner could snap .. so don't take the chance.
getting a good one will cost you from R200 to R300.
