So this vacuum has fit for all of my mason jar soFar, width mouth or regular, really easy to use, just put it on top line it up, press, waited, that’s it. Seals evertime, just once, no repeat needed, a bit of noise, reasonable price, good quality besicallly I am able to use this for other jars too, which is great, wish I had bought this earlier, anyway; great product, good performance. Would I buy this again; I actually expect this to last, but if it does break one day, then sure I will.
