Take care of yourself.
The rest will follow.

I buy, try, and write. My own guides and tips on products I actually use.

✓ Own products and verified recommendations
✓ Personal review of every product
✓ Transparent — ads are always labelled

Three simple steps

Own products and carefully selected recommendations — always with my personal review

STEP 1

I select or create

I browse the market and pick products worth noting — and at the same time I create my own digital guides and materials under the PoLKoR brand.

STEP 2

I test and review

Every product — my own and recommended — goes through my personal review. I write what I actually think, without embellishment. Nothing is here just for the sake of it.

STEP 3

You buy easily

You buy PoLKoR's own products directly on my site. For recommended ones I link directly to the seller's page — no unnecessary steps. I always properly label affiliate links and collaborations.
