I use this brand at home and they have been very reliable.
Brad's Deals Editor David,
Get this TP-Link Kasa Smart WiFi Plug Lite 4-Pack for $24.99 at Amazon after you click the $2 off coupon box below the price. Shipping is free for Prime members, with a free Prime trial, or on orders over $25. Otherwise, it adds $5.99. This was the best price that we found for four by $8. These devices connect to your home WiFi network, and you can turn them on and off using a smartphone or an Amazon Alexa voice-controlled device. Sales tax is charged in most states.
