No offense. I gave the pros and cons to avoid being labled a magicjack fanboy or one of those "one time signup to promote my product" guys. I wouldn't say that its the greatest thing since sliced bread, and I wouldnt say its garbage.
I was just offering a cost effective solution to the OP problem of not being able to connect the 625 to an ethernet connection. I think the MJ is a pretty nifty gadget and am happy with it. I do realize it has its drawback and issues. With the spyware/adware, I haven't confirmed either way but I have my suspicions. IF you're really tech savvy you could extract the sip credentials and use your own ata but MJ may ban your sip creds if they catch you lol.
