Simple and cheap, but fully functional bellows. The only weak point is the thread from the bellows into the tube. The nut is plastic and must be tightened very carefully so that the thread does not skip. I took another spare.
Enostaven in poceni, a popolnoma funkcionalen meh. Edina šibka točka je navoj iz meha v cev. Matica je plastična in jo je treba zelo previdno priviti, da navoj ne preskoči. Vzel sem še enega rezervnega.
