This one is interesting. A hand hand, small footprint, electronic tamper. The inventor takes orders but is normally sold out and is planning to go from kitchen table production (literally) to manufacturing at scale with an upcoming kickstarter campaign.
Unlike the Momentem grinder, the Boston E Tamper is already built with multiple reviews before crowd funding.
and others on YT.
If you already use a self levelling tamper then an electronic tamper won’t improve your espresso but if you have arthritic wrists they are a God send. I have a PuqPress Q2 and will likely replace it with a Boston E Tamper if for no other reason than I need more room on my espresso island for other toys 😃
