$56.99 even with free shipping. i can buy a ledger nano for less than that. hmm. this seems like something that would end up costing more than a real hardware wallet. does it need a TF card? then you have to buy that too.
Aside from Ledger reputation and history, cheapest Ledger HW on it's official website is $79[1]. I also think the page doesn't include tax and shipping fee, although it's at normal price. On a side note, you could build DIY Jade (based on Blockstream Jade[2]) which cost less[3] if you don't mind less feature.
