Question: This is the second power bank I bought in past two month. The first one turns out the capacity is too big to travel by air. I got this one under 10000mAh. Tested a couple of times. Works great. Built in cables very convenient. Comes with a storage pouch good for travel.

Answer: positive


Question: With only a couple of swims under my belt, there is a marked improvement in leakage and fogging. Comfortable on my eye socket/face and the goggles come with additional nose pieces. Product is 'hair friendly' and attractive. It took me a while to figure out the straps, but I 'get it now' and like them.

Answer: positive


Question: This product did not work, the files it produced were corrupted and not readable by any program. Makes me wonder if the positive reviews were real, I don't know how anyone could use this.
