Not worth it but only thing that connects to my lock...so I have to use it. It doesn't stay connected, even if it's near the wireless router. It spends 75% of the time or better disconnected. Not happy, crap product. The lock it is paired with is pretty decent at least.

CON: This does not come with a power adaptor for the USB cable to plug into, (you may be able to plug into your router if you have an available USB port) but if you try to follow as instructed in the instruction to plug into a wall outlet you will have to supply a 5volt 500ma power adaptor (NOT SUPPLIED) *this should be stated in the description as a possible needed option*. PRO: Setup is very easy if you follow the instructions. The Gateway devise is much smaller than I expected, roughly 3" square 1" thick.
