Whooooshhh ... Yep great fun at home at the end of a session of noisy cars - it glides so quietly just a nanometre from the track and is 1 sec quicker than any of my other magless cars (apart from slot.it) on a 6 sec circuit and not much slower than my magnet cars but you need a fine controller like Truspeed or dial the power down to 75%. And it's fairly robust. I keep telling myself they're too expensive but that newish NSR yellow Corvette is hard to ignore.
Cheers
