I recently purchased this product after upgrading my grinder. So far it had worked well and the little magnetic holder attaches perfectly to the Breville Barista Express I have. I love that it’s magnetic and keeps the tool out of the way and in a secure spot. Additionally, they throw in a double sided 3M sticky pad for those who do not have a surface where it can magnetize to. Overall great WDT with a great storage solution.

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.
