I recently discovered this review, and it's one of the best I've found on the internet.

I'm not very surprised by the temperature problem (the radiation shield is really tiny and not very well positioned - is there a way to fix this?). But I'm a bit worried about the rainfall issue. If you take your weather reports seriously, you need to still have a manual rain gauge together with your Vue and correct your rainfall totals... Something I stopped doing after my manual rain gauge broke. But it seems I urgently need to buy a new one if I look at the errors that the Vue reports.

Have to say that I don't fully understand this last post. If you look through the temperature data in the review in detail, any temperature errors (relative to a good-quality traditional screen) really are quite small. In the very worst cases the min and max temperatures are up to 1C out and 95% of the time the errors are <0.5C. I don't think you're going to find any relatively inexpensive automatic weather station that can do better.

And rainfall is a notoriously tricky to measure with an affordable AWS, especially when height/wind considerations are taken into account. Probably the best answer if you ever bought a Vue is to run both Vue and manual gauge in parallel for a decent period, compare the two and then make an appropriate calibration adjustment to the Vue readings.
