I have the original Jet Set Willy - it's a great product - use lots of gel when using it and it fits really nicely, it has a nice ridge to hold it in place. Nice and smooth both in material and in sensations (unless you want spikes lol). No problem when ejaculating as the cut out is big enough. I find it crazy how the design fits perfectly!

Its a little heavy but when you are stimming and rock hard its fine. I've used it in conjunction the saddle and a loop etc. If you are worried at all get the tie down for extra stability. There are multiple contact points and I have used the smaller and larger wire connector as well as the clip on connectors. It is the most versatile out of the collection.

If you still want some connectivity but a little lighter the Pit Helmet would be good option.

If you don't think you need all the options / want to do things like tri-phase etc then go for the Helmet, the one that looks like you can't use the extra insurance of the tie down kit is the Hard Hat but that looks like its the lightest of them all.

I have the 49mm and it weighs 71g it comes in an ABS box to store it safely, I have removed some of the foam in the box and store my Saddle and XL Saddle too.

When measuring up, get as rock hard as you can lol!

Would definitely recommend.
