This piston funnel served its purpose and is very well finished. However Jémettrai 3 reserves: - Complete cleaning of the nozzle (it is enough of a passage under water according to the preparations) forces the piston to force rigid plastic through the orifice, no risk of breakage but perhaps of enlargement of the orifice strength and loss of tightness - Average seal with highly liquid preparations - Difficulty in passing the enough liquid preparations (eg soup to put in a jar, and extend the obligation to create a movement in the funnel so that the descent is done) ... To this by the handling is very good and the product remains strong and very practical.
