Really disappointed because I thought this would last. The gear started slipping after only two months and now it just skips over sections of the rim, leaving jagged sharp edges everywhere. Waste of money.

I've been running two of these Assark units on my property for about a month now. Trigger speed is definitely faster than my old Brownings,

The XL size is perfect for someone taking multiple large capsules. The cold seal system is secure enough that I don't worry about my toddlers accidentally opening it if I leave it on the counter for a second, which was a huge concern for me.

The rib protector provides adequate coverage for recreational leagues. It is not top-tier professional gear, but for the price point, it serves its purpose. Just make sure to double-check the measurements before you buy it.
