There’s still a little summer left for you to enjoy a Pool Jet from I Want One of Those. The Pool Jet is a smaller version of their Sea Scooters, sized for children. It’s safe, because it requires a grip on both handles to engage the power switches. It has a rechargeable battery that’s good for 20 minutes of constant zipping around the pool. The Pool Jet is suitable for ages 5 and up. I Want One of Those sells the Pool Jet for £84.99 (about $132). Delivery is available to the UK, certain European countries, and the US.
