Depends on how your planning on using it, "normal" browsing + a few downloads work great as long as you get used to the lag (2000ms+, 800 kbs Down/20 - 50 kbs Up, as long as you keep it less than 150Mb in 8 Hrs your good), Gaming, Servers, VPNs, etc. are awful due to the major lag (2000ms+). Uploading is also bad due to the dial-up type speeds, Price is also a factor ($600 up-front + $59 a month or $99 up-front + $99 a month for 15 months, then it drops to $59 a month).
Bottom line, if you can get cable or DSL, don't even consider Dway, if you are stuck with Dial-up and don't mind the price, go for it😀
