The ePlay leather cage is designed to be worn around the penis or penis and testicles for e-stim play, providing stimulation to the penis. This is a set geared towards beginners to more advanced users I think. It is used with the e-stim control box, which has a modular jack to use with different stimulation devices. It seems also to be geared towards BDSM type play in look and design. Can be used with or without a partner.

The cage is made of leather and might have a very minute odor, but I don't recall noticing it. It is as you would expect, slightly textured and fairly firm (not stretchy, but bendable). There is no real smell. Inside there are metal rivets for transmitting the current to your genitals and two snaps for adjusting to your size/ desired tightness.

The leather feels comfortable on your body and is arousing as it presses against your skin. There are of course wires hanging off as you will be plugged into a control box during use. You simply plug the jack into one of the sockets in the control box and away you go.

The size and shape should fit most people. There were no instructions, but I think this device can be worn one of two ways. Both straps around the penis shaft or one around the testicles and shaft and the other just around the shaft.
The ball strap fits girth from approx 1 3/4" to 2", the penis strap is from about 1 1/4" to 1 1/2";

Using the behind the testes method I was able to secure both rings snugly and just barely. For both straps around the penis the larger one was a tad loose. It's probably not the intended design, but if you have a hugely thick penis, it would work. (2"+ diameter).

The toy is easy to hide or travel with, but you would want to put in a checked bag as it's not discreet.

I tried using this dry and with water-based lube, but didn't find the sensation I had hoped for. It didn't feel like I was getting stimulation at all contact points. Instead it sorta felt like hot spots of shock on tap mode and those sensations centered more on the backside of the testicles, rather than the penis. Also for me the sensation felt more on the pain side of the spectrum, rather than the pleasure side.

The toy is silent like all e-stim devices. The only noise might be screaming if you got more charge than you had expected.

The toy is easy to use. You can wash with soap and water or toy cleaner and dry afterwords. The device should be used with water-based lube to help with the conduction. There were no instructions, but that is a general rule of e-stim.

Plastic bag w/bar code. Very minimal. No manual.
