Great if it's available

I've implemented a custom stopwatch for Roller Derby on this platform. It's the perfect fit, has all the hardware capabilities i need, and the price is not too outrageous. If anything, i would give it a bigger battery and make the power button safer.

Sadly, the availability ist not great at the time of writing this review, the product has been out of stock since shortly after the launch and for quite a while now. I was lucky to be able to order a few extra units on Ali Express for a highter price. I would love to make a larger order, so all my colleagues can have their own stopwatches using my code.
