The TEW-645UB is, as I have already mentioned, a very large adapter. The majority of the space inside the 6.5 inch tube is antenna. This is where the TEW-645UB stands out over just about every other USB adapter. When you consider the size and strength of the antenna, it is no surprise that TRENDNet is claiming better range.
Unfortunately, while the length of the TEW-645UB helps with range, it actually limits portability.
I attempted to use the TEW-645UB without the stand and found it to be very cumbersome. There was simply no way to use the TEW-645UB while supporting a laptop on your lap or a soft surface. With the TEW-645UB plugged into the back of my 17" ASUS G2S-X1, it would fall or get knocked out of the socket and to restore the connection, in many cases, I would have to reboot. I tried with the adapter in the side USB port with the same results.
If you have the space on a hard surface (like a coffee table) you could use the TEW-645UB plugged directly in, but at that point you might just as well use the stand.
