Pool Jet lets you go underwater with little effort

Check out the £84.99 Pool Jet that lets you make your way across the pool without much effort from you, as all you need to do is grab hold of it and you’re good to go. This is more or less the lesser sibling of the Sea Scooter, and since it is pool-based, you won’t have to worry about making your way to the mouths of other dangerous sea creatures. It has enough juice to last for up to 20 minutes of constant use, and don’t worry about the safety of your child using this since it will require the pressing of two buttons to keep it going, so if one hand happens to slip off the button, the Pool Jet will stop jus about immediately. The rule of diminishing returns applies here as usual, since a charging time of approximately 4.5 hours yields the aforementioned 20-minute of swim time. At least you can make summer more fun for the little ones in your home pool with this, eh?
