It was 1:00am in the morning on12/28/23 when I needed to add air to our Sleep Number bed, but to our dismay was unable to access the inflation control (inflate/deflate) on the manufactures app on my cell phone. All our app data presets were lost. I was infuriated and had an idea to go on-line and search for a replacement air pump with wired controls. There it was, REM Air System. It matched what I wanted to accomplish. NO App, Dual Wired Controls with readout, quiet operation, ease of installation, ease of use and affordable. I placed an order at 3:15am that same morning, received the REM Air System the next day and in about a half an hour had the new unit up an operating. Everything worked perfectly and we were very, very happy. I will recommend this replacement REM Air System to anyone who will listen. We give it a 5 Star rating.
