None that i can think of.
I use this whenever I play. It makes your gun easier to hold and it can hold speedball markers which most straps cannot Some can but its kinda jury riged. Trust me i have tried most of them. If you are a scenerio player this is a must have item. If your in the woods or on the speedball field you can use these to. I would only get one if you arent an aggressive player in speedball and hung back alot. It could cause problems. This is the original and its the best!
Dont got one get one cant afford to get one.....save your money and get one.
