The product itself is very durable for the price compared to the Opteka X-Grip. At first I thought the handle was completely made of hard plastic, but it turns out the part where you hold the Cam Caddie has a rubbery material very good and comfortable for holding. It's also very good with keeping attachments in place.
Stability: If you are using a DSLR (I use the Canon T3i), you're going to need to buy more accessories besides the Cam Caddie Scorpion itself. It's going to be very shaky if held by one hand, and still a little bit weird when you hold it with two. If you're going to buy this for a DSLR, buy the Cold Shoe Attachment too (it's the green thing. But if you're using any other light weight video cameras, this should do pretty fine.
I found myself filming more stable footage without the Cam Caddie than with the Cam Caddie.
If you're using this for skateboarding, you're going to have to buy the Cold Shoe Attachment. If you really need a handle, this is the product to buy (and the attachments of course.) This is a great entry-level handle for new camera users. A satisfactory product.
I'm giving this 4 stars because it requires you to buy the Cold Shoe Attachment to improve the stability for DSLRs.
