The short version
Three value-tier panels at three different price points. Hooga is pure budget. Bon Charge is wellness-brand mid-tier. Infraredi is large-panel value at the top of the under-$1,000 tier.
When Hooga HG500 is the right pick
If budget is the deciding factor and you want verified two-wavelength specs at the lowest legitimate price, Hooga is the right shape. Most first-time buyers should start here.
When Bon Charge is the right pick
If you are in an EU/AU market and want a panel from an established wellness brand, Bon Charge is the right shape. The $550 over Hooga buys brand recognition and somewhat more premium build, not better specs.
When Infraredi Pro 1500 is the right pick
If you want the largest half-body coverage and broadest spectrum under $1,000, Infraredi is the right shape. Closest thing to MitoPRO at a $200 discount.
