Good quality and reliabilty
The camera is very easy to use and the quality of the vide is very good. This is an excellent product for the cost. I used the camera as an attachment on my bow during hunting season and it worked well in all types of weather. There are a variety of attachments that allow set up on almost every type of platform.

Best over the ear headphones!
I love these headphones! First, I am huge Marshall fan. My brother plays out of a Marshall stack. So I know the quality of sound. My wife has a Bluetooth speaker from Marshall as well. I have been eyeing these for quite a while now. Saw a price drop. Jumped on them immediately. The battery… DAMN! It’s nuts on how long the battery lasts. The control knob is easy to learn and use. And most importantly, they sound superb!

Really like how the batteries lasted. I used it to see what is hanging around my country cabin where there is no wifi.

Best headphones
Bought these bad boys and I have been happy ever since I used to use skull candy ear buds but I always end up losing them. Many years ago I bought the jaybird blue tooth wireless earbuds then my cat had kittens and they found them and destroyed them. Battery life is excellent sound feels like you are in the middle of the show. I mostly listen to Black Metal
