I received this package as a component of an even larger package (this plus chalk, bag, and harness). I've been using this package for indoor climbing. The belay device is almost perfect. Of course, loading is extremely easy, and the rope moves VERY smoothly. It's a significant improvement over a Mad Rock model that I have also used frequently. It's also true that it will stop a fall with little effort. The only (slight) issue is that it requires a little bit more force to maintain the locked off rope position than some others, surely because of the smooth, low-friction finish. The Screwgate carabiner is great for one-handed operation. Once the lock has been twisted into the unlocked position, it stays there. The gate can then open and close freely, until you decide to twist the locking mechanism back into the locked position. It takes two fingers to lock-unlock, and then your hands are free to manipulate the gate, items attached to the biner, etc. They're both great items, so if you can save a little money by getting them both together, then I say do it!
