Mojack differences

[tmangarage]

sorry to repost- but maybe someone visiting this thread knows?
I noticed on Mojack website the specs on the 550 and HDL seem almost the same. But normally the 550 is usually around $100 or more cheaper than the HDL version. Right now the 550 is only $139 at Tractor Supply while the HDL is at $379 at Home Depot.

Is there a substantial quality difference between the two. Just wondering why the price difference if the specs seem the same. thanks

From the looks of it, the HDL is a Home Depot item and the 550 is a Tractor Supply one.

True each is sold at a different store chain, but with the specs still makes no sense why the other is so much more.
Lots of videos on the HD version, not so much on the TS version. Oh well, the mystery continues I guess
