This company is honestly better than all the other major manufacturers we've purchased from. When our unit encountered a technical issue after a winter in storage, customer service stepped in and almost immediately resolved. A new unit was arriving at our door before we even realized it. A huge relief and a great experience! And we LOVE the app-enabled product. Being able to set our times & temps away from home has made such a difference to our comfort. Knowing our dog is safe when we aren't home and it won't over heat does us so much good. Wouldn't recommend you buy anywhere or anything else.
