This is a neat remote controlled robot according to the hype surrounding it. And truth be told, it could be... if.... IF .... you get one that actually works properly.
My first R2Q5 wouldn't charge properly. There was no indication anywhere on the robot that it was charging. So, I went back to the store I purchased it from and had a horrible experience with Best Buy's customer service simply trying to get an even exchange. A customer service manager got involved and finally managed to straighten out the exchange. That in of itself really shows how poor the customer service has become at Best Buy when a manager has to get involved for something as simple as an even exchange.
The second robot I got does charge properly. I noticed that a small light is near the charging port, something I did not see on my first robot. It glows orange when charging, then green when it's fully charged. I think Sphero should have thrown in some animation on the robot to show it's charging, like they did with BB8 when it's charging properly.
The app controlling the droid what I would call merely ok. I would have liked to have seen a battery measure on the app showing how much charge is left on the robot before a recharge is necessary. If I missed finding that in the app, let me know for my future reference.
R2Q5 also seems like it's a bit unbalanced when it's moving around. I think perhaps it may be a design fault that the robot has, I don't know.
The price on the robot is crazy at over $100+. I bought this on clearance for $49.99 before sales tax but even at that price point I feel it's still too high. I guess Best Buy can charge what they want for this particular robot as it's their exclusive.
So overall, I'd have to say I'm less than impressed. To be fair, I suppose it's just an average remote controlled novelty with its various boops, beeps and other noises it makes and nothing more beyond that, much like the previous BB8 robot.
And yes, I would recommend getting an extended warranty on it should you decide to buy it. Why? There's no way to replace the rechargeable battery on this item so once it quits holding a charge, you have nothing more than a paperweight. Also, the tracks on R2Q5 appear to be made from a very thin type of rubber so once they break that also may not be reparable. Keep those things in mind along with the poor customer service at Best Buy when making your decision on buying this product for yourself.
