Good purchase
By Verified Buyer (from WA) on 8/10/2016
This was a replacement for an identical unit (8 years old) that was giving odd alarms due to a bad float switch. For the price it made sense to buy the complete unit instead of just the separate float switch. The float switch solved the problem and now I have a spare alarm unit in case one of two (One 20 years old and one 8 years) at my home fails although I doubt one will. All of these units are built by SJE Rhombus and the newer ones are all plastic but they still seem to work OK. Pricing was very good, the product shipped as promised and was packaged well. Would do business with PexU again.

Works Well
By Verified Buyer (from Dana Point, CA) on 7/29/2016
After just one overflow, you WILL want this monitor. Easy to install, built well and the best thing is you will never worry again when you flush the toilet.ANYONE with a sewage ejector needs one of these as i learned the hard way.
