I have Dash-Mate's Bill. On the 350 and the WindStar. I've had several brands thru the years and can't say One is any better than the other, other than the 'ol.. You Get What you Pay For.
My current Dash-Mate fits very well, stays in place with Velcro tabs. I like a dash cover for it's sound deadening qualities and it eliminates Glare & Reflection.
Beware of the material they're made of, and the thread used. I had a very nice THICK one that was a Free-bee from my Dealer.. Locally Made (Fresno). The California Sun got to it in about 2 Summers. The "Tijuana Tuck'n Roll" quality deal.(remember that ?)
The Dash-Mate's have been on the 350 for 6 years and the WindStar for 5.. Both are still in very good shape.
I bought ours, Touchy Feely, at Pep Boys. I'm not an E-bay guy.
