Tyent Edge vs Enagic (Kangen) SD501
The Tyent Edge and Enagic SD501 are both countertop ionizers, but the Tyent wins on nearly every measurable spec for less money. The Edge packs 9 plates, dual .01µ filtration, lifetime labor coverage, and a 75-day trial for ~$1,485 less than the SD501's MLM-inflated ~$3,980 price. The SD501's case rests on Japanese manufacturing legacy and decades of field reliability — not hydrogen output, filtration depth, or warranty length. Buy the Edge if you want modern Tyent performance without Kangen markup; buy the SD501 only if Kangen brand loyalty and distributor relationships are your primary drivers.
