JoeFrex - 51 mm Tamper Base KNOCK

All KNOCK bottom parts have a flat pressing surface to press the coffee grounds.

Why the name Knock?

After pressing the coffee grounds for the first time, lightly knock on the side of the portafilter to dislodge any remaining grounds on the side. It can then be pressed again. To avoid using the base of the tamper or the wooden handle for this light tap on the portafilter, risking damage to both the tamper and the portafilter handle, you can now knock with the silicone ring integrated into the base.

Great Bag
Color: Brown
Okay I was hesitant on buying this bag. Finally did it. I can say OMG this bag is everything. I have recently started to love carrying the backpack bags as everyday bags. The one I have is a little big so looking for a smaller one. This one is more medium size with plenty of pockets. The color was beautiful. It seems it will hold up for a while.

Perfection, Or Close to It
Color: Black
I absolutely love this bag! Now that my child is a toddler, I’ve found it easiest to combine my purse and diaper bag into one bag. I no longer need to lug around a huge diaper bag full of bottles, blankets, etc., but I did need enough room to store toddler essentials (a few diapers, a changing pad, wipes, diaper cream, snacks, snack, and more snacks, medicine, a couple of wash cloths, and a toy) plus my essentials (wallet, keys, lotion, lip balm, eye drops, kindle). This has room enough for all of those things without it being an oversized purse or a full sized backpack. A lot of purses will state that they have a lot of different compartments, but the compartments won’t be a size that makes it actually useful, but this purse is different. Each compartment is spacious. Plus, the compartment on the back that’s a secure place for your phone or wallet is actually big enough to store things without having to squeeze it in! If I could give this purse 6 stars, I would. My only qualm is wishing the straps were a different material so that they wouldn’t readjust the size so easily. But if you slide the metal part up toward the decorative leather part of the strap, the leather adds friction and stops it from sliding down.

Beautiful Color
Color: Green
This was a very nice purse. It seemed to be of good quality and I loved the color. I did return it because it was just too big for my tastes and needs. I loved the functionality of it with all the pockets, but didn't want to carry around a backpack sized purse. I would recommend it for anyone who likes large purses. Seller was wonderful to work with.
