It's cheaper than a "tech" scooter.
Comparing recreational scooters to technical scooters is a waste of time for anything other than highlighting that they're not comparable in any way.
It's quite a bit more expensive than other recreational scooters that it compares more closely with. If they're aiming to be the cheapest in their segment, they're going to have to get the price under (or at least close to) the $399 that seadoo gti sells for ($450 msrp, $399 at most stores).
Otherwise you're paying nearly twice as much for a slower device with less range whose only advantage is being 14 lbs lighter on land.
I know, there are some for whom price is no object, and others who consider $350 money well spent to drop 14 lbs dry weight (0lbs in the water).
It might mean trouble for pegasus thruster. That scooter is far more expensive ($4k on leisurepro) slower, same battery life, and heavier. Pegasus does go far deeper with a rating for 325'. I doubt anyone going to 325 is going to be using anything other than fins or a technical scooter.
So, there IS a market for this, but It's already pretty saturated. I think these guys have an uphill battle. Especially with the name recognition (and retail outlets) that seadoo enjoys or the well placed marketing spots that pegasus buys.
