The grinder worked out well

I used it to grind for drip coffee and put maybe 2 pounds through it and the battery was still above 85% at the end of the weekend. I had to grind in 2-3 batches at a time as the drip coffee maker was large and the hopper on the grinder is small but thats not a big deal. For a single serving it’s perfect. The speed for pour over / drip was perfectly fine and the grind consistency was nice. The grind adjustment is also very convenient (I like that it’s not under the grinder). There was 35 people at camp and everyone really liked it.

T38 Plus is great value with some caveats

I use the T38 Plus as a secondary single-dose grinder for espresso (eg for decaf). It performs very well. There are two significant disappointments for me: the plastic base looks very cheap, and the magnetic dosing cup just does not snap into place, which can lead to grounds spilling because of the very tight chute design.

Looks great. Haven’t had a chance to use it yet as the power plug is not suited to our sockets. I’ll try to find an adapter.

Exactly what I was looking for!

This grinder was worth the wait! Easy to use, compact, yet still holds 30g of beans, which was what I had searched for in a smaller affordable grinder. It's fairly quiet, easy to clean, and seems to effortlessly grind through a full hopper of beans. I couldn't be more satisfied with it.
