Where did you get the idea that its not as secure? I dont think thats accurate unless there was a security flaw that was exposed that I missed.
It's not that are not secure, It's simply they are not 'that' secure compared to Ledger nano S, I'm not speaking from experience but from what I've seen from different individual speaking about this subject on Reddit.
For just a bit of premium over the original price, many are selling at ebay. They are selling the oldest and cheapest ledger wallet but better than nothing and you do not need to wait that much, just the shipping time from the seller.
I prefer buying from the company it self or from their official re-sellers because you can't really know for sure If someone did something to the device that could get your funds compromised at some point when you are buying from an individual.
