My last one equipped with manaul pumping lasted over 17 years (which was Japan made), if not more (I bought it when I was really young). My wife got rid of it couple of years ago (while I was working overseas), only because of she wanted a newer model. Nothing wrong with the old one, except the manual pump was a little bit less efficiency compared to when it was new. Our current one is a similar model (probably the same) and it has been sound since. The only complaint from my wife against the newer design was; since now it is equipped with electronic dispensary system, it means the pump won't work when you have a power-out (that make sense of course). Whereas, the old ones you can still manually pump the water out. Honestly, I take my hat off to this company and the brand is highly regarded in Japan.
Just double checked of mine, in fact it is the 3 liter model with all the same functions. One thing worth mentioning is, the cafè (slow flow) function is not really that useful in terms of coffee brewing. This is because there is very limited space below the outflow nozzle (eventhough the front panel is concave), which means there isn't much room to maneuver your brewing apparatus. On the other hand, with the size and weight of 4 liters capacity, it is not pracrical to lift and hold it above any coffee filter/funnel/jugs (to me, my 3 liter is already quite heavy when refill.)
