MDPI Opiniones

MDPI offered to make a video FOR FREE to illustrate our paper about decision change. I wrote a quite difficult script and when their first version of the video did not convey the message right, the team was willing to shoot it all over again, although officially, only minor glitches are fixed. The result is video 1729 on encyclopedia dot pub. For the animations and visuals, they made excellent choices and the voice over is intentionally slow because the proposal is hard to understand at first sight and hearing. If you are honoured to get such an offer, I highly recommend accepting it. Thanks again to the team.

Spam sending website. Not to be trusted

Abysmal, treats their staff like garbage and highly unethical platform in regard to lack of rigorous checks on papers that are published, so long as the money is paid to get it out there.

Don't waste your time with this company! After the interview, they won't give you any feedback! So unprofessional!

Predatory publisher who let go through very poor manuscripts rejected by serious publishers. Want to publish quickly without a serious review process? MDPI is for you: just pay the fees and your manuscript will be online in a few days. Are you a serious scientists? Stay away from these predators.

Doesn't honor unsubscription requests (spammer).

Invites me to become reviewer or even editor for random topics where I have absolutely no expertise. That is certainly not what scientific peer review is supposed to be like. This sheds a very bad light on the already low reputation of this publisher.

There are many predatory publishers out there, and MDPI is apparently one of them.
