I ordered the wrong size by mistake, I was able to exchange for the correct size in 48 hours without a hassle, The product? It's an Adidas, I expected quality, well... I've got it, it's a very confortable shoe.
positive

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.
negative

I don't do presentations every day, or even every week or month, so I thought with a nice review, most people getting the issues they had rectified, that this would be a great purchase. After 1 use, and a battery change to make sure that wasn't the issue, when I plug the USB dongle into the computer and turn it on it just flashes green once for any button I press. It will not connect with the computer, and the the laser pointer doesn't even work which would at least give me some use with my pets. This is a YMMV type of purchase it seems.
