If you would like to know which gadget I think is the coolest and most useful, it would be the cellphone jammers. This piece of nifty device can block cellphone signals and stop cellphone users from using their mobile phones. Why do I think it is the most useful? Well, don’t you just hate those idiots talking loudly on their phones like they own the whole world? How about those morons who talk on their mobiles during a show in the cinemas? And those little kids on the bus with their irritating ringtones which “rings” like 10 times per minute, probably they have thousands of friends who can’t wait to call them? Won’t it be just great if you could stop all those? Yes, those cellphone jammers would work. You won’t be listening to people grumbling about their mother-in-law coming to visit anymore! Hooray!

However, I think they are illegal in many countries. It makes sense to make them illegal because it is very prone to abuse. Not to mention that mobile operators could be broke if everyone carries one cellphone jammer. However, I think those people who talk on the phones like nobody’s business should be made illegal too. Perhaps cinema operators themselves should install cellphone jammers in the cinemas so as to ensure that their customers can watch the show in peace. That would be justified. And they aren’t that expensive. Everyone would appreciate a little peace and quiet once in a while.
