Extech is looking for 3000 followers to it's twitter account, at which point they'll pick one and give them a FLIR i3 color IR camera (google's telling me it's worth about $1200). AFAIK, eligibility is worldwide. They're at around 350 now, so a lot of us get a chance to win!
Extech rules when it comes to promotional contests - hands down!
1 in 3000 chance of $1200 worth of equipment? 40 cents to follow them? I have had better deals from people trying increasing their feedback numbers on ebay.
I completely understand where you're coming from, but since I do follow them I can say they hardly ever post. Nothing like,say, adafruit who blasts 5 once a day. I can't even remember the last time extech 'tweeted'. Considering that, it takes about a second to follow them. If you win, great! If not, did you really lose anything? To each his own, though. I could really use a thermal camera so...
