An XRF gun is $35,000. A lab panel is $200 a sample. This is $75, forever.
Same question, answered at home, as many times as you want.

What would a lab even be testing?
Illustrative estimate. The kit answers it for real, without the invoice.
Everything in the $75 kit.
Reagent, light, applicator, and instructions. Reusable for life, refills are inexpensive. One purchase, every surface you will ever question.
What it actually does.
It is binary.
Lead glows green under the light. No lead, no glow. There is no chart to interpret and no number to second guess.
30 seconds.
Spray or drip, shine the light, look. You are not sending anything to a lab and you are not waiting days for a result.
Reusable for life.
One kit, every surface, every thrifted find, every imported dish, for as long as you own it. Refills are cheap.
Built on real chemistry.
A methylammonium bromide reagent forms a bright fluorescent perovskite the instant it meets lead. This is published science, not a color-change guess.
