Quick review - I got the red one, firstly have to say it is very weighty and I think actually quite well made, not at all cheap plastic, so not like a 'kids toy', its a very hard plastic top and the movement of the top seemed ok to me, but having said that - it isn't at all shiny (which didnt bother me tbh!). Only issue I have is that its really really noisy! Its having to go back as my cat is just not impressed with the noise and theres no way I can put her through that everytime I use it! I didnt put anything in the bowl so can't comment on it not reaching the sides although from what I could see it didnt look like it would have a problem.
I still think this is an ok machine for the money but my cat comes first (even before the boyfriend! lol) so its going back. Hope this helps anyone wavering on buying etc. xx
