Disappointing.  Worked for 11 months, then died.
We were really pleased with this product at first.  It allowed us to monitor my father's movements in bed and sitting where ever we were in the house.  We'd replaced the batteries before, but never otherwise had a problem.  Last night, it just quit working.  Tried batteries we had in the house.  Nope.  So, we bought new batteries.  No go.  I'd have expected a $150 product to last longer than a year, but it didn't - it's especially surprising because we were not hard on these.  We didn't move them, fold them, expose them to water or animals... nothing.  My dad's a small man 125 lbs, so weight's not an issue.  I want something wireless, but I want something that will last.
