Well, you do admit that a company just giving you a free item of nearly a thousand dollars value is going to raise some suspicion? I have returned many things purchased through Amazon going back 10 years and I cannot recall a single time where I was told to keep the item. Here are the last 5 things I returned to Amazon and all of them had to be returned:
Fumoto F-109N Engine Oil Drain Valve
2.7" LCD Dash Cam FHD 1080P Dashboard Camera
Narciso Rodriguez for Her Limited Edition Eau de Parfum Spray with Atomizer, 2.5 Ounce
RIDGID Wet Dry Vacuums VAC4000
Fitbit Blaze Smart Fitness Watch, Blue, Silver, Large
I'm not saying this to call you out but to show you how fantastical that sounds. Thus the reason for the skepticism.
