There is a bit of information missing - these are not NIB - they have been bought at auction, estate sale, swap meets, etc. Why do I say this?  They have a disclaimer that they have no idea what condition they are in. The picture is of a NIB item of that type. Guessing that these have the firmware that is subject to "many second" brown outs.

IMO you get what you pay for.

You could always send it to Horizon service and have them upgrade the firmware. It's up to you whether you say you are the original purchaser or that it was bought used with a disclaimer.
