A question of weight ...

The volume of Trixie impeller during operation is mainly due to the weight of the animal. I did it for gerbils with a good 70g weight and one with almost 110g. If the mouse is 70g in the wheel, you can hear almost no noise when running at 110g mouse wheel vibrates strongly and is also very noisy, especially when the mouse is properly gas. The frame construction of the foot is not ideal in this respect.

Otherwise it is easy to clean and my mice nibble not even after half a year on it. I would buy it again, but people with rodents than 100g (and sensitive ears) should maybe even watch the big wheel of Karlie - which I already had, that's still been silent even in my "heavy" mouse. Does it have the disadvantage that it is clean (smells like urine) hardly.
