Honeywell Home RTH221B 1 Week Programmable Thermostat Reviews
Absolutely stellar experience with Honeywell Store! I recently purchased a substantial number of thermostats for an apartment community and had them shipped to a property in another state. From start to finish, the process was seamless. There was no delay in shipping, which was incredibly important for our project timeline. The online payment process was secure and straightforward, giving us peace of mind. On top of all this, we received a significant discount by ordering in bulk, which was a fantastic bonus. Honeywell Store exceeded our expectations, and we couldn't be happier with the service. Highly recommended!
