how long has your BRS 2-part doser lasted?

Hi, I've been using BRS 2-part dosers for the past 5 months without problems. But recently one has become loud. So I was just checking to see if there is an average life for these pumps. Thanks

I voted but like you stated my pump has got loud to the point that I replaced it however it never failed before I took it out of service.
