Unfortunately I don’t see Hanna re-designing the packets anytime soon. That said, get a small funnel off Amazon. It works well. When I first saw the packets, I thought this is a mess in the making. Luckily I do have a small funnel. When doing multiple testing with other Hanna testers, I just wipe it down and stick a q-tip in the base to swab out any residue. When all done, I chuck it in the dishwasher.While we're at it...
Replace the reagent packets with those long vertical pouches you find at coffee shops. The geometry and luck involved with perfectly opening those square packets is too much work. Use the sugar packet design and just tear off the top and pour in.
AND - while we're at it - forget the ping, just work in some bluetooth/wifi and hit an app on my phone with the measurements when done. Keeps a log etc.
