Query: At first, OK but...

I used the original original Brita for many years. I drink about 3 glasses a day and the dog about one.I liked this model because it was slim and I had a small fridge. But after 2 years of use, actually sooner, I realized that it is just a little too small and you spend a lot of time filling the darn thing up all the time.Finally, one day, the white insert fell on the floor during a filter change. Parts of it broke off. I thought this was rather odd. The whole thing should be indestructible. It is not.So when my local store had a sale on Brita, I picked up the current basic standard Brita and it is just big enough that I don't feel like I am filling it all the time.So the Slim is just too slim (unless you are really not a big water drinker and petite?), it seems much more fragile than other models.
