Is the RENPHO Smart Scale worth it for the price?

Across the reviewers we read, RENPHO's entry smart scale gets praise for the app, FSA/HSA eligibility, and weight accuracy at a low price, and TechRadar's review calls it accurate and feature-rich for the money. The recurring criticism, repeated on r/Fitness, r/loseit, and r/MacroFactor, is that the body-composition estimates shouldn't be trusted in absolute terms.
