I love it!
Value for Money
TDSmaker's big templates library includes designs for all industries. I have horrible design skills, but templates saved me.
You can get control over the datasheets by assigning permissions to other coworkers. You can even integrate the documents to your website automatically.
TDSmaker can track the data for viewed or downloaded data-sheets and you can generate custom reports, and analyze most viewed data-sheets.
I also liked their customer service.
They have a free consultation, which is a good option if you are very new to datasheets.
Creating a personal design from scratch is hard.
The interface is available only in Turkish and English.
