Not very reliable
The wand only lasted 5 months.  The button on the wand that stops the water flow became stuck, so no water would come out.  After some coercing I managed to get the blue plastic button to pop up.  However the water still didn't flow as it appears the internal valve was stuck.  I ordered a replacement from another vendor on Amazon.  It arrived today.  Hopefully this wand will last longer.  The original worked for over 2 years before having a problem.  Gave it an overall 2-Stars as the item worked well for 5 months of daily use.
Rating: 2 stars
