Perfect WDT tool
Best WDT I’ve found. Love that it includes 0.3mm needles (as I’ve found that 0.4mm needles push the grounds around too much), and the stand is very clever. It knocks off the residual grounds on the needles and is easy to use. As far as WDT tools go, I can’t imagine anything better.
