    Fragile item arrived very well packaged. The delivery was timely. I think Unbeatable Sales did an outstanding job. The transaction did not require any communication with Unbeatable Sales. **I did attempt to contact Unbeatable Sales several times prior to purchase to answer some questions, however, no one answered at the indicated phone. The end result was still outstanding service from Unbeatable Sales.

    5-STAR SELLER! Exceptional value in this purchase. This is my second (ame product) purchase from this seller in less than two months. This dumbbell is brand new, wrapped in plastic, and very securely padded and packaged for shipping. Communication with this seller was nearly instantaneous (response) and always accommodating to my delivery expectations. Highly Recommend This Seller.

    Good seller. The Fireplace cap got banged up in shipping. I needed to take the top cap off and bang it into shape with a hammer. Not the seller's fault but some bubble wrap inside the package might mitigate Fed Ex's rough handling. No one besides the birds and the satellites will ever see the dents or the hammering out of said dents. I recommend this seller for price and fast shipping.

    good thermostat but some improvements needed.

    easy to set up and install. user friendly app is provided for the unit. However, some improvements can be made for trend data. My previous wifi thermostats do provide temperature change historical chart. This help me to judge performance of my heating system while I was traveling overseas during winter season. Sensi thermostat only provides temperature reading at the time when I open the app. I have no way to know the readings one hour ago unless I keep watching it.

  • 3rd Sensi, and would buy again.

    Very good product, without problem. Setup was a little challenging, but their techs helped us get it working on our system. We own 3, at different locations. Would buy a gain.

  • I have been using Sensi ST-55s in three ...

    I have been using Sensi ST-55s in three residential places, two states, and with two internet providers. I have had no problems with this item or its installation. It is a quality product, and I am now using it with two wire condensation boilers without a C-wire.
