Excellent Product, Great Price, On-time Delivery

from Aledo, TX – Verified Buyer

We needed to replace the smoke alarms and these were a great value for the money. Paid approximately 1/3 less than the price at our local 'big box' home improvement store. Wayfair delivered on time, as promised and the shipment was easy to track.
