So folks, I explained to my wife the importance of window contacts. Finally, FINALLY, hehehe, I got an approval for the purchase. As you know, only surface mount is applicable to my window contacts. I also only know GRI brands. Yesterday, I bought 2 piece of window contacts just for my testing and learning. Now, I need the final one that I will mount. I would like to get recommendations from you which you think is a reliable window contact. Does window contacts perform the same?
