I had experience of having portable Hibrew, IKAPE is different level. Love it
IKAPE V5 Coffee Tamper, Click Espresso Calibrated Tamper Sound Feedback
very satisfied with K2 pro.
I can try many 58mm espresso tools,
And trying to dial-in and optimize for best shot is very fun!
I wish it has a internal pressure gauge, or updating apps to show actual real-time pressure.
