Do I need an expensive 8-electrode scale?

8-electrode scales with handles (like the GE and RENPHO models) add segmental analysis, but the reviewers we read are split on whether the extra cost buys meaningfully better accuracy. Some community testers found 8-electrode units more stable but still pessimistic versus DEXA. If you mainly want reliable weight tracking, a budget 4-electrode scale delivers most of the practical value.
