After 5 years of daily use, I just had my first maintenance issue which required swapping out the diverter cartridge. I'd swapped out this part on my two previous faucets, so this wasn't new to me. I was happy to find out this is a common part available at specialty plumbing stores, although Stephen at Vigo tech support had the part in stock and shipped it to me in just a couple days, along with some helpful advice. A solid, well-built piece of hardware, although part of me wishes this model allowed for simultaneous use of overhead and front jets as I suspect the VG08005 does.
