Great product.  Great Amazon seller.  This product gives you a low profile, attractive way to mount your Ez Pass to your windshield.  I just hated how the ugly white Ez Pass transponder looked affixed to my windshield.  Now it's cleverly hidden inside this black pouch.  NOTE:  The pouch does NOT impede the operation of the transponder in any way.  I'd like to add that the suction cups that hold the pouch to the windshield are strong and effective.  Through hot summer days and cold winter nights, the suction cups have not failed and the pouch has stayed in place.  * * * * * Five Stars for this simple buy unique and effective product.
