I ordered 3 for my grandchildren. For the moment just checked the resistance to inflation because I will not use them before three months, I had to buy separately an electric blower, I paid less than 10 at Leclerc Sport, they swell in record time and take good air. Like everyone else I have found that strong smell, I left them to air a week and the smell is significantly dissipated without disappearing. inflation and deflation manual is very explicit and following the instructions, so tighten the exhaust valve before inflating and there is no loss of air. Deflation is done alone and is very fast.
