I don't, but my parents have a Hozelock system which is timer co trolled and has loads of pipes going from the tap it's attached to. I know they are happy with that as they have many plants in pots and are often away for a long time and it saves them hours with a watering can.
We're hoping to get a new patio done soon and definitely will get a Hozelock system when it's done, or maybe even get some of the pipes laid under the paving to reach pots furthest away.
