Not my experiences at all.
After reading the OPs few posts about his Eclipse I started to wonder if he just got a lemon or I got very lucky. I have had mine in everyday use for a few months now and I don't have any issue. Of course I wish the CPU was a touch faster but it becomes a issue for me so rarely I never really think about it.
The dual sim was a must for me and it works flawlessly. I don't have dropped calls and oddly enough only ONE person I ever call to has an issue with me hearing them or them hearing me and ironcially they are using an HTC Hero.
I would say I am a 9/10 pleased with this phone of course the cheap price helps but it took very little tinkering on my part to make things work and there are some things that work differently than other android phones but different does not mean worse... simply different. Some are better for my personal tastes and some are worse.
I didn't have the shipping taxes issue either as I live in Thailand so it took two days to get here and cost me 100 baht (about 3 bucks) for the duty so all in all count me as a very happy customer of the phone.
