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.
