Testimonials

I have been using Vintasoft Twain since 2004 and it has been solid as a rock since it was first specially adapted for my particular requirements. Unlike many companies support from the team and in particular Alex is outstanding. I have no hesitation in recommending the company and its products.

I was evaluating a bunch of twain components for .NET but NONE of the Components were so simple and comfortable to handle as the Vintasoft Twain Control is!

Marcus Lauermann
Naome Ltd.
I just wanted to extend my appreciation for your excellent support and solid product. Your twain product is much better than the product we were working with previously and your support response and quality is 100% better.

Got it downloaded and we will put that to work right away! We purchased a .Net twain control set for a custom written application using cameras about three years ago. We found Vintasoft in an Internet search. When we updating the software, we purchased the newer version that we needed. Our developer had said it was well written code. Thank you once again.
