Love it. Perfect for being on the go. Stadiums, theatres, crowded environments. Fits in your palm and if you go without stem you can much more easily conceal.
I suggest carrying several batteries when on the go. MAKE SURE your batteries are NiMH & at least 2000mAh. Use a SLOW charger. It is possible to get USB chargers for the NiMH batteries. The USB adapter will not only power off of a USB port on your Computer, Xbox, etc. but can also be powered using your cigarette adapter in your vehicle if you have an adapter that allows for USB connections (many Smartphones, iPods, Zunes, Walkmans, etc. will have this type of converter included in a travel kit, or you can find them super cheap online.) You MUST strip your batteries of the plastic casig before they will fit in your LB unless you have Modified the box itself.
I heard that there is an AC adapter being released sometime in the near future, and specifically early to Beta Testers. This will allow you to save on recharges for your batteries which will make their lifespan increase. I hope to acquire one of these, or create one of my own soon.
It's also possible to connect a bag and fill it by connecting a bag to the stem and gently blowing into the hole on the backside (opposite side of the stem). If you're savvy enough you can use an external fan to accomplish this same task. And if you really want to get deep, you can connect multiple boxes together using flexible stems and a splitter attachment (Y, T, 4-way, 5-way, etc.).
There are many mods that can be done on your Launch Box, but be careful as many will VOID your warranty. If you have some mechanical and technical skill and know a little about woodworking you should be able to come up with endless ideas for modifications.
