I have my up's and down's with these lenses. I do have the odd pair that will last 3 weeks without any issues and then I will have a pair that feels dirty and sticky after 2-3 days. I know exactly what you are talking about.

I soak my lenses overnight always. But sometimes I find that they are still horribly dirty after 10 hours of soaking.

I have also had issues with blurry vision from time to time. Almost as if they aren't centred properly.

I will give it another pair or two before I run to the doctor with complaints though, I still have 3 boxes of each eye left.
