Perfect for my needs -- I wanted a dual drain outlet, one for washer, one for water softener discharge and this worked out perfectly.  You need an adapter for the water softener drain hole but found one here on Amazon.  PEX connection was great.  Note: best to crimp PEX lines to faucets before mounting box and attaching drain lines in order to give you more room to get the crimping tool in.
