Please, folks, before you buy this. We bought one for our grandson last time out (different model - SLS). The failure rate is very high. His never even worked. After going 'round and 'round with Woot, they finally ended up refunding our money. However, EVERYONE missed the point: He got a bright red toy, that never worked. So, unless you are prepared to go find one elsewhere for a whole lot more money (as we ended up having to do), don't buy this. This whole deal pretty much turned me off of woot.
