To make matters worse, the battery pack was much larger than I hoped. As advertised, it holds three AAA batteries, but it is by no means slim and easy to conceal, totaling about twice the size of the battery bay itself. And it's heavy. Fully stocked with batteries, it's not easily hidden, as it would pull down the fabric if kept in the "small pocket sewn inside the shirt." (I'm guessing that's why it features a belt clip - I honestly can't imagine anyone wearing this shirt with that relatively large battery pack concealed within. It would look ludicrous.)
All told, I was completely underwhelmed. I guess the technology for this sort of shirt hasn't reached the point yet where it can be combined with clothing of this sort to form a truly wearable, fashionable piece of apparel.
On the upside, the "decal" is detachable, and the battery pack and wiring are removable - allowing for transplantation of the nifty wi-fi signal detector onto items more suitable to the unit's relative bulk and prominence. I'm thinking it might serve better adorning my canvas book bag, or perhaps stuck to a laptop cover - I'm not sure yet where I'm going to put it. I'm quietly awaiting a moment of inspiration. (The shirt, at this point, is a loss - without the "decal" the velcro-like material and hole for the connector are plainly visible. Unless I stick something to its front to hide these.)
I wouldn't recommend that anyone buy this shirt (or any of the similar "Interactive T-Shirts") until the price comes down a bit more or the technology reaches the point where it isn't such a detriment to the shirts' appearance. (Unless, like me, you plan to scrap the shirt and use the interactive placards elsewhere. Or unless, unlike me, you are so jazzed about the idea of wearing an interactive shirt that the fashion disaster created by the unattractive placard and bulky battery pack doesn't bother you.)
