goodluck in the contest!

The Wi-fire does in fact work, increasing signal maybe 50%, but not nearly as good as mfgr claims. A flimsy design requires rubber bands or duct tape to secure it, plus its software is buggy, causing me to have to reinstall it more than once to get my computer to run it reliably.
Worst problem came when ordering a second unit for a friend (not knowing at the time that better, competitive products are now available) but it arrived DOA. I had to send several emails and leave phone messages to try to get the thing replaced, without results, and finally asked for an RMA. Suddenly, six weeks later a new unit–instead of a refund–arrived, but with no reimbursement for shipping their defective product back.
Compared to several other online electronic companies I’ve bought from, Wi-Fire’s customer service is very poor, about the same as the stability of the device. I recommend checking Amazon and other web sources for better solutions than this one for improving improve Wifi reception.
