"Excelab 7.0 is perfect product, daily used very efficiently while saving unbelievable time in calculations and result analyzing."
"ExcelWorks calculus add-in has been incredibly helpful.... The ExcelWorks support have also been incredibly helpful, responding to any queries I had in a quick and effective manor. I would most definitely recommend this add-in to anyone considering."
".. the ability to share models and results in a highly familiar platform..with near-zero learning-curve in using the program, have compelled me to break from the past and put in the effort to move our models to ExceLab."
"It is easy to learn and support provided by the admin staff is very nice. If anyone working on multi PDEs equation problems, just try this one you will love this solver"
"I found excel-works derivative functions quite useful. I was particularly pleased with the prompt response for assistance when I required some technical issues to be resolved....."
