Endurance clamps Nipple clamps discontinued

My first toy to review from EdenFantasys was for the Endurance Clamps. I was pretty excited about getting them. I mean, come on, me and nipple clamps go together like whip cream and sex!Unfortunately, I don't have a positive review for my first toy. Sad day indeed when a set of nipple clamps is rejected by my pain-loving boobies.Upon my initial opening of the package, I was already confused. I'd never seen a set of clamps shaped quite like these. They only appear to open one way so I can only assume that I was doing it right, but to be honest, I searched for another way to open them because it didn't *seem* right.They are clumsy to use. Attempting to open them quite often had them twisting out of my fingers, snapping shut, and falling out of my grip. Anyone who uses nipple clamps knows that twisting, snapping, and falling are three words that should not ever describe nipple clamp use. We want nipple pain, yes, but not nipple amputation!I can't even do an accurate review of how they felt on my nipples because I couldn't get them on my nipples. They don't open wide enough for those of us with, shall we say, generous nipples. But clamping it on my fingers left me with these thoughts:It's an exceptionally strong clamp. Because of how the clamping surfaces meet (it's a rather thin, long bit fitting into an indented bit), it felt more like a pair of scissors than the erotic squeezing sensation I prefer in nipple clamps.It also tended to push my finger up and out of the clamp rather than provide an even surface pressure. I suspect that if you could get a nipple in there, it would pinch very tightly at the bottom, probably popping the nipple out at the top.I didn't like the dull gray surface color of the clamps. Maybe I'm spoiled on bling, being a diva and all, but I like shiny metals that glint in the light. Not the brushed, dull gray look of a tool. The chain is pretty and shiny though!I give these clamps zero stars as they are completely unusable for me.
