Review on 🦈 Inflatable Flying Shark Air Swimmer by Christopher Ward

DOES NOT FLOAT AT HEIGHT. I inflated it at a party shop (making sure it was filled with good quality helium as much as possible) and carefully followed the instructions to place the motors in the right spot based on height. However, the motors were so heavy that once I attached them, the shark sank and never resurfaced. The maximum altitude given in the instructions is 2000 feet. I live at over 5000 feet. The product description on Revain should be clearer. The buyer should also beware of the ridiculously short return window, which I missed.
