After much research I bought the blue cam R1 for my two boys. They've had it a week, it had a full charge when we first got it, and hasn't needed charging since! I'm so impressed. It's been used daily and travelled very long distances as the kids have been practicing. Can safely say this is the best purchase ever. I've already recommended Rolab to some friends and family. The bag and remote control are fantastic add ons. This has been up and down hills, along bumpy surfaces, smooth surfaces, used indoors. The kids have made each other obstacle courses and timed each other completing them, all on their R1. They're currently saving their money so they can purchase another one! These are quick to charge, hold their charge for days, are fantastic quality, encourage the kids to get off their consoles and are extremely well made. So far, it still looks brand new, despite being bumped and bashed on all sorts of surfaces. This passes all the safety requirements, which was one of my main reasons for purchasing from Rolab. The kids have a great time on it and I have the reassurance of knowing it meets the highest safety standards. It's a win win really. My only negative comment is that I regret not buying one sooner! Thank you Rolab for a great product, speedily delivered and provides hours of fun.
