Product review (1 stars): Third unit failed - each one right at 2 years!
My first unit of this same model lasted 2 years until the transmitter failed. I assumed I had bad luck and bought a new one after noticing it had gone on sale. The new transmitter also failed after 10 months despite (both) of them mounted outdoors protected from the elements. After 2 days of troubleshooting and following their online instructions I determined it simply failed and called for a replacement under warranty. I waited a full hour on hold only to finally reach a customer service rep who didn't like it that I wouldn't give him my email address. I became frustrated with his attitude and decided that for $9.95 (what I paid) that I didn't need to subject myself to this and can look for a different brand. I did enjoy the display unit but the product quality appears poor if it doesn't last 2 years.

Update - my third unit failed - outside transmitter not being received. Same issue each time, each time right around 2 year mark. Each time no warranty support since it has a 1 year warranty. I have to move on to another brand.
