Kook pro double decker. Bat pocket ripped off with the pull handle first time I used it!
Several gms not lasting more than 3 months. One returned as arrived as it was broke before use.
2 slazengers disentegrate.
And a mongoose bag that the lid tore off, although that because I grabbed it instead of the handle(so my fault)
I bought a b3 duffle bag to keep bats in end of last season, it ended up doing this season too as I just prefer duffles. It's very simple, so not much to break, and nothing has as off yet. Thankfully.
