This is a solid feeling WDT tool. It has a good weight in the hand. While it may not have the fancy push down and auto rotating mechanism, it still functions very well. The stainless steel needles are long and can easily reach the bottom of the portafilter with a magnetic dosing funnel attached. It's a solid WDT tool for the price. Easy to clean, easy to use, looks and feel premium.

Does a great job!

I gave it as part of a gift to my son and he loves it. It’s used every week and does a great job.

It’s fine.

I would prefer the needles be straight, and I couldn’t make them that way. The method for replacing the needles is … fine. I would also prefer the base of the holder be closed rather than open. It works well, but didn’t meet my expectations.

Elegant! 👍👍

I didnt just want a WDT tool. They basically all do the same job. I wanted something that was elegant and beautiful to look at. This is it! No plastic here. The base is solid metal and thick heavy at the bottom so as to not get knocked over. Top is a real nice smooth wood.

Wonderful WDT

I was not convinced this WDT would make much of a difference but it does. It is easy to declump espresso clumps. It is nice having the clever stand to store it in.
