Jammermfg

I have no idea which one I received because it's not listed on their website...so I believe the previous 1-star review that they get cheap jammers to sell from other sites/manufacturers. There were no instructions or a description included in package. It worked well for 2 weeks and then stopped being reliable. My phone wasn't even blocked when I had it in the same room as the jammer. I believe within a week it will completely stop working. Do I think I'm going to get my money back? Of course, not.
Unfortunately, cheap garbage and unreliable products made in China.

Here's how this site works:

1) Products at a good discount from other sites
2) Fake generic reviews
3) Supposed option to use credit card. Message that bank refused, when you get no indication from your credit card that there was any attempted activity
4) Option to wire funds, info only available on a temporary web page
5) Instructions incomplete, so bank can't send. Follow up with jammermfg and they will alter one word in the instructions
6) No package? A follow up email gets the response "Chip delayed, will send package today"
7) No package, wired funds gone

In summary, go with a legit site that uses an actual payment processor!
