We have had this less than 4 months and have just had problems with it.  We had it professionally installed.  Water pressure stinks.  And it’s not our pipes.  Great pressure everywhere else.  Now it won’t turn off all the way when you touch it.  Still drips.   Today it won’t have let you use the touch feature at all.  And we have changed the batteries.  So we have another plumber coming today to change it out.  Expensive for just 4 months.  I would NOT purchase this faucet.
