First the remote. There are 2 speed control settings. The fast speed isn't too bad. I'd say if you're trying to use it in a pool, you'd want the slow speed. We use it in a lake, so the fast speed is no problem at all. You can trim the boat on the remote if it's tracking to the left or right, which is great, but we actually don't find the need to do it much because it's pretty straight right out of the box and doesn't seem to get knocked out of alignment very easily.
Sometimes it can pick up some moss if it's close to the surface, but we've always been fortunate that it just kind of falls off when you get it back near the shore. it hasn't wrapped up in the prop yet. Not to worry though, the boat did come with one extra prop in the event of disaster.
Battery life is very good. Probably about 20 minutes for each battery. It comes with 2, which is something I appreciate about a couple other DEERC R/C products I've gotten; they really seem to have realistic play time in mind when designing products. There's an audible beep that is very easy to hear so there's no question when it's time to maneuver back to shore. They don't take terribly long to charge either, maybe a couple hours.
The self-righting feature is phenomenal. We don't use it much, because the boat really is pretty stable, but when it DOES capsize, the self-righting mechanism automatically does its thing and the boat is back upright within a split second. There must be sensors somewhere that tell it to go. On sensors...
NOTE - There is a sensor on the bottom of the boat that must be wet in order for the boat to work. SO if you take it out of the box and put the battery in and try to test when it's dry to make sure it's working, it won't. Just put it in water and it'll pair/work just fine!
I'm not sure what more to say. My son loves it, I'll even use it for myself. It's a great toy especially for a lake or small pond. Highly recommend! DEERC made another good one with this.
