This is the second Aieve product I’ve purchased, after a very good experience with their XL espresso cooling ball. This WDT tool isn’t flashy, it doesn’t look like a praying mantis or deploy like a switchblade; but it does exactly what it’s supposed to do. The tool sits in a nicely weighted base that protects the needles from bending, which is a big improvement over the magnetic “floating” styles. The base has enough weight to stay put, and it’s easy to remove and return the tool without it tipping or sliding around. The base itself fits nicely in my tamping station. It also comes with replacement needles, which are simple to swap out when needed. If you’ve been going down the rabbit hole comparing every WDT tool out there, this is a straightforward, well-designed option at a very reasonable price.

Solid 4mm WDT tool with a solid stand and a magnet option for some machines.

Color: Black

Solid WDT tool with good hand feel and convenient counter top stand. 4mm needles and it works fine. 10 of these 4mm needles adequately stir the espresso in the portafilter. No real complaints about build quality. I attached the included magnet. There are many people who have identified that the magnet is not strong. This is true but it depends on the materials on your espresso machine or grinder. On stainless steel units (unpainted or thinly painted) it has good adhesion. On units that might have used thick paint ( which shouldn't be compromised) it may not stick well. So I took a star off--I do have a stainless steel Espresso machine and it sticks fine. It also stuck ok to my refrigerator , microwave and airfryer. If your espresso station is near other appliances---well there you go--also it does show that it "can stick" to fairly common other magnetic materials. My refrigerator is coated in white . I was going to simply buy acupuncture needles, a wine cork and make one of these but add those costs together and heck $9 for this unit with a stand was a great deal.

Great little tool

Color: Black

It’s a cheap tool but can actually make an impact on the coffee. Been using for a few months and still works great.
