We just installed this faucet and so far are quite pleased with the finish, quality and performance. However, I would like to see an option or accessory that offers a transformer/rechargable battery pack as a replacement for the standard battery pack, as the cable on the pack is too short and I have to get on my knees to access it under the sink. With an optional transformer/rechargable battery pack I would not have to be concerned about having spare batteries and would have a battery backup if the power fails.
