It works great. Has very nice appearance. Simple to use. The build is quality done. Could be a little bigger so a phone could fit but otherwise nice product

I bought two of these boxes, and I just received them the other day. My vehicle is a 2014 Jeep Grand Cherokee SRT that uses a keyfob. For my vehicle, I keep the keyfob in my pocket and can open and lock my doors and back hatch by touching the door or hatch handles. In addition, when I start my vehicle by push button, and my foot is on the brake, the vehicle checks to see if the keyfob is inside the vehicle. If it is not, then the dashboard will display "No keyfob in vehicle", and not start the vehicle. I put one of my keyfobs in one of the boxes, closed it up, and tried to open the doors and the hatch. As I was trying to open the doors and hatch, I rotated the box in various directions, but was never able to open the doors or hatch . I tried this with both boxes, and I was unable to open the doors or hatch with either box. So I opened up the top of one of the boxes, with the keyfob in it, and I was easily able to open up the door with no trouble. I then tried to start the vehicle with the keyfob inside the fully closed box, which was inside the vehicle. Again I rotated the box, while repeatedly trying to start the vehicle. No luck, the vehicle would not start. I open up the box and tried again, and the vehicle immediately started up. So in summary. The box (actually both boxes) I bought works exactly as described. It is a nice size, well made, and a reasonable priced. It works perfectly for my vehicle and keyfobs.
