My kids have several DEERC cars, a plane and a helicopter, so we jumped at the chance to try their RC boats. All of the DEERC products have been excellent quality and these boats are no exception! You get TWO boats, making it ideal for racing with a friend.We took these to a nearby large lake and played around with them for about 30 minutes, and despite lots of high speed racing we still didn't use up a whole battery, so battery life is excellent. Four batteries are included (one for each boat plus a spare for each). The lake was relatively calm but still had some waves, and neither boat capsized once so they are well weighted in the water.The remote controls work pretty much the same way as RC cars, so controlling the boats was easy to get the hang of. These boats zip through the water at an impressive speed and they are very agile with a tight turning radius.If I had to pick a complaint about these it would be that I wish the range were longer. The range is 80m (262 feet), which is not bad but I enjoyed driving the boat quite far out into the lake and then worrying about going too far, and if you exceed the range then there's not much hope of getting the boat back. There is a light that flashes on the controller when you're getting the boat close to the end of its range, so at least you get a warning.These are excellent quality toy boats. You get a lot of fun for a very reasonable price. Highly recommended!
