The life of the OXO Good Grips Compact Toilet Brush & Canister really depends on how you use and maintain it.

The manufacturer mentions that the brush head is replaceable, which is pretty handy. It means you don't need to toss the whole thing when the bristles get worn out or too dirty—you can just swap out the brush head. This definitely helps in making it last longer.

So, how long it lasts really comes down to how often you use it and when you decide to replace the brush head.
