OK, buckle up. Pessimistic feedback coming in... :P

I think the diagonal banner looks cool, but afterwards you can't read the name of the thing anymore and so it is not practical in my opinion.

Why is the crypotsteel banner not in the top? Startign your text 2mm after your banner doesn't look very nice too me. (Ok now that I actually red the text at the top I understand why you done it. Maybe at least make the spacing bigger between the text and your websit's banner?)

I like the sliding pictures and I think its good that you provide a link when you click on it.

You should consider writing about how one uses such a cryptosteel device. How do you screw it together?
Why is this product under the tap services? Might a tab "Products" be better?

This looks nice. Nice side infos there.

Maybe increase the spacing between the text and the picture a bit (picture could be smaller).

BTW: I kinda like the coinbase review page: https://cryptogoodies.com/review-coinbase/ It is kinda funny :P . Its good to know that you have 85% experience as a office helper... :P
