I have one (actually two as the first one broke). They are made out of plastic and you have to be very careful when folding them down to be sure that the sliding feature is slid the way for folding. If not you will have to buy another one as that breaks them. Great idea but aluminum would have been nicer.

i've had good luck with the powerbelt aero 245s. only real solution is take both out to the range and see what works best in your gun.

The powerbelt loads much easier, but both can be loaded with the factory ramrod with no problems. The 245 Aero shot great out to about 150 yards then started to fall apart (badly), where the 200g Shockwave was consistently accurate out to 200 yards. I should mention that the above info is using 120g loose pyrodex powder. Bottom line for me is that I will never again shoot a powerbelt through my Omega if I have the option of shooting the Shockwave. For the newbies, clean your barrel often (like between each shot) when doing your initial sighting in that will help with loading your projectile.
