Ive had this for a few days, and its great so far, way sturdier than I expected. Ive been a Reef flip flop fan for years and these didnt disappoint. Because of some of the reviews (and an inability to figure out the sizing chart), I erred on the side of going slightly bigger. The resistance is horrible and the fan doesn?t seem or function as an air bike is supposed to do. The wall charger has some weight and feels heavy duty. I work 12hrs a day and getting out of my boots in the evening is something I look forward to. There is a also a more medium-sized section and a small one that is very soft (great for phones + earbuds). I?ve fully charged my phone and ear buds to full charge 4 times so far and the case still has charge. Sound now only comes from one side. So we?ll start the review with the title.
