[Q]: Only looks good in the picture, and the materials are very rough, stained and cheap. The copper is a lining not pure. I should've know due to low price but even at the price it is definitely very poor workmanship and not worthwhile. Now I have spend more money getting something better so as they say; better to spend wisely then hunt for bargains.
[A]: negative

[Q]: This is our second Netvue camera, first was a indoor one, the picture quality and voice are perfect. It's super easy to install and customer service is great if you have any question on the product. Love it so much getting 3 more as Christmas gifts.
[A]: positive

[Q]: I read a lot about this product before buying it and it was amazing! My Morgan had her hold rear-end covered in rain rot from this horrible Tennessee weather this year, and I didn't know what to do, I thought I'd have a huge vet bill and a lot of maintenance, but I sprayed this all on her and gently rubbed it in good and groomed her, after using it twice in two days it was 100% gone. Absolutely get this product if you need something like this for your fur-children.
[A]:
positive
