So Sorry, I was busy being on vacation, LOL
We didn't use it ALL the time, but never had a problem when we did use it. I had it set on all our netbooks and my Droid and they picked up the signal with no problem. Since we were staying next door to DVCZerfs, I texted and offered use of the signal but he didn't use it - he had already paid Disney, sadly.
I definitely used it in the van while driving along 95, and used it in our room both at the Contemporary and OKW. Dowload times were great and we never lost the signal.
It was really nice not having to check the clock when we used it, just fire it up whenever. DD used it for videos and had no buffering issues. I mostly used it for e-mail, traffic sites (sometimes a little too late, LOL) and news sites.
I honestly wouldn't say there was any bad or ugly about it, other than making sure you don't overpay for it. I got mine from eBay for around $60, retail is $150 which is a little high for me. I liked the fact that we could share the signal, although most times we DID just do one at a time anyway.
The only issue I would mention is that Virgin Mobile customer service really stinks. They are the cookie cutter, out of the country, follow this list/flowchart to try and solve any problems. They honestly have NO IDEA what they are talking about. You need to be able to set up the wireless network on your own. I did ours and it was really easy.
I didn't need customer service on the internet, but I did try and use them on my phone when I first activated it. If I could have, I would have returned it. We joked in our house about the customer service rep named "Peggy" from that commercial.
