Aqua Marina Betta VT K2 - first impressions

Recently I was deciding which inflatable kayak to buy (Decathlon Itiwit, Sevylor Colorado or Aqua Marine K2) and there was a lack of ifnormations or reviews, so I took my iPhone out of the pocket and made some shots to help other people. Edit: The problem was not in valves, I had to replace the pump with another one at the local retailer. The original pump pressed too much on valves and made them locked in deflate position.
