[Q]: Perfect as a personal item. NOT considered a carry on and you won't be charged for it! Wonderful when flying certain carriers that charge for everything!
[A]: positive

[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.
[A]: positive

[Q]: These knives are extremely sharp, and I love having non serrated steak knives. They do a great job with cutting, and while i've done my own sharpening with a whetstone, its not really required. I just wanted to have extra sharp knives. They are very light but they are very durable and useful. The block isn't that great its kind of a hollow plastic, but its just a storing mechanism.
[A]:
positive
