[Q]: I'm so glad I stumbled across this product, because it has seriously improved my WiFi speed. Using it on an older laptop , I noticed that WiFi speed was faster than the built-in WiFi . I later tried it on an older desktop and it was very fast as well. An excellent product!
[A]: positive

[Q]: Fast shipment and easy to install. I don't have any mechanic experience and even have my friend install the back off camera for my car last year. My friend is out of town for his business trip and I have to install it by myself and I did it just in 30 minutes!!! It worth my dollars and quality is good over my expectation. I am still exploring all the features of this new car radio (sorry I am not a very high tech person) but so far it meets all my needs and functioned very well for me. Quick and easy to connect with my smartphone.
[A]: positive

[Q]: I like to draw and occasionally multitask, and this case is really built for that purpose. I love the little pencil slot to store it once you're done drawing or etc. The magnetic stand is awesome, very sturdy, stays in place. It can also mount onto your fridge, in case you wanted to leave notes or cook a recipe. I'd definitely recommend this case to any iPad owner.
[A]:
positive
