"Great performance, nice look - happy camper..."4.5 starson by jkline67
Pros: First, I like the way it looks, second I like the way it works - once you get going it's pretty fast, but what surprised me the most is how smooth the hand off is compared to my last modem, this is by far much better.
Cons: The software on this is robust and takes a really long time to load, and I probably wouldn't use half the features. If it weren't for this part of the process, this product would be a 5 in my book.
Summary: I chose this device because the rep at Sprint couldn't articulate the difference between the U250 and the U600, and I didn't like the U250 design, so I went with the U600. I liked the way it looks and it's fairly smaller and lighter than the U250 and U301 that I saw.
After about 10 minutes of installing software the modem looks for 4G first and if it doesn't find it, the modem will look for 3G service, while switching between 3G and 4G there's a little hick up, but not like before when you lose your enttire session, so in that regard it is much better.
Bottom-line, the product is better than my previous dual-mode modem. The hand off is better, the updates are much easier to load, and the device's speed performance is awesome.
