Is the Acaia Pearl worth it over a cheap coffee scale?

If you want fast 0.1 g readings and app flow graphs, yes. For simple weighing, a basic scale does the job for far less.

Does it work with espresso machines?

Yes. It fits under most drip trays and its timer covers shot timing, though check clearance on low machines.

No. Weighing, tare and the timer work on the scale alone. The app adds flow graphs and brew logging.

It has a built-in rechargeable battery charged over USB, so you never buy disposable cells.

4.4 lb, enough for a brewer, carafe and coffee. It is not meant for large batch weighing.
