I have the Cradlepoint CTR350. I use it with the Cricket Calcomp A600 USB modem. I have it wired to my desktop and have my laptop using it wirelessly. I'm afraid to leave it in there constantly and it burn out, and unplug it and re-apply my laptop and desktop to it every time I get on the computer. Any Cricket employees or customers who are using this product or know of it are welcome to answer! Thanks!
