[EX Q]: Simplest, yet sophisticated smart plug. I was looking such outdoor smart plugs so that I do not have to go all around the house to turn on and off the decorative lights for festival time. These were just the right stuff. It worked just fine, 1) Easy installation - The app is self explanatory on how to install 2) Quick and fast connection 3) I have plugs all around the home and have no issues in connecting them.
[EX A]: positive

[EX Q]: This brush is a snow and ice BEAST! It is, perhaps, the most solidly built brush and scraper, with easy extension and easy rotation of the brush to change its angle relative to the shaft. As it is a new purchase for me, I'll have to update this later in the snow season. And, frankly, I'm hoping that I won't need it again this season. But I am prepared! Fast shipping, and excellent follow-up by the sender. highly recommended.
[EX A]: positive

[EX Q]: I have had these for quite some time now and they really do not disappoint. The sound quality is great and I have had no issues with them since I purchased them about a year or so ago. I'm not really a sound professional but I did my research and found that this brand was one of the top tier players in the game. I would definitely recommend these to anyone who wants great headphones.

positive
