Hi Joost,

Thank you for your great feedback — wonderful to hear that the engine runs smoother and that you clearly felt the difference. That’s exactly what we design our oils for.

Sorry that the delivery took a bit longer than expected. We’re working on improving this so future orders arrive faster, while keeping the same careful packaging quality.

Thanks again for your trust in Xenum!

The Xenum Team.

Dear Janusz,

We are sorry to hear that the bottle was damaged during transport. Fortunately, it did not leak, which confirms the quality of our packaging. We take great pride in maintaining the highest quality standards for both our products and packaging.

We would be happy to replace the damaged packaging free of charge. If you have already used the product, we sincerely hope that its performance exceeded a two-star experience.

Please note that transportation is handled by an external logistics partner, but we will certainly report this issue to them to help prevent future occurrences.

If there’s anything else we can do for you, please let us know.

Best regards,

Xenum Customer Care

Basic-Simple=Quick-Stressfree

1-Very basic and simple Web Site that does the buying experience easy and head ache less (Literally 2min. and product purchased).
2-Buying without registration (simply perfect)
3-Other option that i have loved is the posibility to avoid the mandatorty,obligatory,anoying and simply STUPID News Leters that will (in my case) automatically ticked to go directly in Spam oder Trash Bin. IF a Coustomer WANT SOMETHING.... dont worry, it will chek and look your Web Site, its not need to send every month E-mails.
