This toy meet all of my expectations (and my partners'!), but we all feel the "fit & finish" leaves much to be desired, *especially* at this price. The hinged rings themselves are well made & solid. The screws & holes for closing do not have alignment guides & one has to really work to not strip the screws as they are tightened. Worst, though, is the flimsy feel of the long screws that do the stretching... They need a weld not just at the bottom of the base ring, but also at the top for better stability. And they are too short - ~12cm. The spiked testicle plate is beyond shaky & gets in the way as stretching starts. Finally, the spikes should be pointed. Just my humble opinion. All in all it feels like this is a prototype of a great toy idea
This is a well made, easy to use, easy to clean product. The shape makes it easy to manuever, the fact it is made out of steel makes it easy to clean and sterilize. It is not an unmanageable weight or size. It is durable and also is designed in such a way that it is safe to use.
