If youbwant to set up a multisig, they have great guide shown to don't hat with sparrow or specter. Also somehow, the wallet itself will confirm that it's part of that multisig. I haven't tried that out yet but was thinking about it.

Other than that they are really easy to use, and I would think they have all the feature one would need. 

The price is 150usd, maybe that is the reason? 

 I don't think the prices was the issue. The price of the Bitkey was the same. I think it's more about the steps involved. As another user pointed out, I may need to force myself to learn with small amounts and count it as the cost of learning now for greater piece of mind later.  

 The guy math-hew kratter mentioned about the bitkey the flaw of having no display, therefore being vulnerable to certain attack vectors.....
I also liked the bitkey. But if you write it down

1 key in a hot wallet
1 key in a cold wallet with no display 
1 key in someone else's hands...

All together the solution is kind of good but it feels still a bit awkward....
