Stopped working after 2 months, so I check the batteries.Yep, batteries are dead already but 1 of the springs has detached itself (see picture).long story but final answer from Sado is that since it's over 30 days old I have to pay $4.95 for shipping of a new one.I guess it's my fault that they made a piece of junk.Buyer Beware!
