The CHK-SHIELD US Blog is self-sustained by the Amazon-Affiliate-Partner-Program. So whenever you recognize an "available on Amazon" button, an affiliate link is used and we get a little bit refunded by Amazon if you place an order there within 24 hours. Also, most product pictures are linked in this way.
Unfortunately, the refunds from this source are very low. To produce a blog-post about an outdoor or tactical gear product or other topics around 10$ are needed to cover all costs.
So feel free to place a donation. By the way, if you have any topics, we shall cover let us know.
