[EX Q]: For hours I have tried to figure out this machine. It finally got the best of me. It is being returned. I can't figure out how to bind 8 1/2 x 11 size paper. It leaves a half punched hole either at the top or the bottom of the paper and the combs they give you are too long for this size paper as well.
[EX A]: negative

[EX 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.
[EX A]: positive

[EX Q]: I used these to get through busy airports on vacation and I also used it when my two year old and I were swimming in the ocean. He has no fear and will swim out as far as he can go. The wrist links keep our hands free and I like how the adult wrist link comes off quickly if I need it to, while the toddler end is tougher to take off. These are very sturdy, don't get tangled up, and with the two lengths they are be exactly what I needed no matter the situation. The whistles might be good for an older child, but needless to say, with a two year old, I threw the whistles away. They are LOUD.
[EX A]:
positive
