and how none of them are as expensive as Sooloos.
Sooloos doesn't have to be better, though it has to be good enough. The luxury product sector is about ensuring that your product is perceived to be the best. And if it is not expensive enough, it won't be.
I've probably posted this before, but I remember hearing a story about a US sales/marketing consultant who raised the price of his client's (UK) products by a factor of six, simply because they were being perceived as "cheap". After he did, sales took off.
