I bought the 3 pack and had no issue with the first 2. Went to use the third and it is NOT the same and didn't seal off the water. Waste of money. Only OEM for me from now on

Ex Output:
negative

Love these sheets! They arrived very quickly. After the initial wash they softened right up. I love the quilted end to the fitted sheet, makes it easy to put on and a snug fit!

Ironically for a zwave device this paired and connected to smartthings with no hassle at all. Unfortunatly it does not work as expected. it shows the window as open when opened less than 50% of the time. I can actually here the magnetic switch click when it works and not click when it does not. Maybe i got a lemon but I suspect this is just poor quality and design. i tried it it multiple locations on the window, and just to be sure I tried it on my desk with the magnet and switch right next to each other, aligned perfectly. It still registered an open less than 50% of the times tried.

Ex Output:
negative
