Bought this on sale. I have also outfit my parents house in TP link Kasa stuff. Compared to some of the other Tuya based platforms... the build quality is superior, and the app experience is better for a beginner. Hard not to like it. Some cheaper models do include a built in USB charger for a cheaper total price, hence the 4 star value but 5 star product. I will continue to expand our Kasa range knowing i have the security and quality of TP link.
