Super happy with my first purchase from aleko which was the 13.8 inflatable boat. My second purchase was the 8.5 inflatable and I’m not nearly as happy I can’t get the thing to keep air in it it’s driving me nuts the rear left tube..... I checked the valve but that seems to work fine I dunno maybe leaking from a seam? Has been inflated and then put onto the top of my cruiser I own up here in Alaska. Has never been used.
