I use this with the RodeoH harness; it fits nicely and is great for thrusting, but the heaviness of the toy weighs the panties down. If you're planning on using this with a harness, I'd suggest to get one with an interchangeable O-ring, rather than the panty style. The Cush itself is great for strap-on use.
The Cush's size surprised me. It's definitely thick, so if you're used to smaller dildos, you should be wary -- I'd not recommend this for beginners. However, I purposefully bought this because I was seeking a thicker toy. (It's definitely what I hoped for!)
The Cush has subtle ridges that give some variety to the shaft. It's pretty solid so it doesn't bend a lot. However, the material is cush-y (HA!), so it doesn't feel hard when it's inside. It's both long and thick, which makes it perfect for a satisfying ride.
It is easy to clean, pretty to look at, and a lot of fun.
