[EX 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.
[EX A]: positive

[EX Q]: I never wanted to be a dog parent that needed one of these, but here I am. I have a year old puppy that will not listen when it comes to eating things he's not supposed to outside. It's super easy to use and I love that there are different settings. I mostly use the vibrate but when I do need to use shock I have to use at least 80 for my dog to even notice it. My use of the collar is to have my dog drop whatever is in his mouth from a distance so a lower setting might work for your dog. There's a charge port to put the collar and remote on which is awesome. The collar is also super long but you can trim it to fit.
[EX A]: positive

[EX Q]: It is a fish pole for wiring. I use it with a USB mini camera to catch ends of wiring in tight, inaccessible places. Works well. Seems sturdy, but time will tell. Like the extra ends.
[EX A]:
positive
