Best WDT Tool Every Espresso Lover Needs
This tool is so easy to use. It comes with a handy holder you can stick on the side of your machine and even replacement needles for the tool itself. I’ve had the tool for over a year now have not had to replace any of the needles! The 3M adhesive on the back of the holder is amazing quality. It won’t come off your machine. The tool itself helps take out the guesswork with your espresso shot, making sure the grounds are evenly distributed before you tamp.

Very nice but no replacement needles?!?!
The tool looks and feels great. It is very well crafted and packaged. The mount works well (both magnetic and tape). I would rate 5 stars except that it did NOT come with the replacement needles specifically called out in the description.

Good value
I like how it comes with the magnet mount as well as a sticky backed metal piece to use. It has a nice weight to it too, it doesn’t feel cheap.

Get this for your coffee bar
Perfect for your grounded coffee. I attached this to my ninja machine, and this was so good. It is out available for next use. No problems with it falling down.

High Quality
This tool has very nice weight (all metal) and very nice machined finish. Feels very premium without the premium price. Well thought out with the magnetic base or 3m double sided tape included. Nice that they included replacement needles. Would definitely buy again.
