Customer's deadlines still exist with what is often a reduced staff. Developers want to jump into a product, pull out what they need, and use it to get the job done… painlessly, quickly and reliably. We accomplish this for them with a step-by-step developer's guide, lots of samples, an online knowledge base that's exceptional, and 60 days of free support. The feedback from our beta testers was high praise for our staff, our product, our documentation, samples and gratitude for how quickly they were able to accomplish their coding objectives.'
