We have been using their tools for over a year now, and we are very pleased with them. Cost is part of what competition charges. They work great, they look beautiful, and this reduced our development, so our project was completed two months before the expected, even when learning new tools.
The learning curve is a little steep, but this applies to any of the comparable packages. Technical support sucks, only by email. When we first bought it, they had a support forum, and you could find most of your answers on the forum, but unfortunately they ended the hit. Now it takes several days to get an answer. But when running the entire application, we had many pages to work on, waiting for answers. Most of the time they pointed out problems or told us how to solve them. And I sent them a lot of messages telling them to ignore previous requests, finding answers on the Internet.
Their examples are simple, and if your needs are simple, there will be enough. If you are creating a full-blown application to replace an outdated application and running your business, for example, we did, you need better support. However, it was well spent money. We use the grid and filters to search our client database of 200,000 records and we can usually find the person we need in less than 10 keystrokes by name. Performance is very good on our intranet.
I note that when I thought I discovered software bugs, it was just me. The comma where the period should be, poor capitalization, improper use of functions, etc. Javascript is very sensitive to syntax and is not friendly with error messages, so much time was spent on code execution to detect not so obvious errors.
And our requirements probably go beyond the majority of people's needs, our main screen has a combination of superform and 7 data grids, each of which gives a modal form for data entry, all on the same web page. But it works well. In total, we have about 60 pages of data entry and another 60 pages of reports that we created using the oBout tools. Report pages allow users to set report criteria (for example, dates, customers, products, etc., using pop-ups, calendars, switches, etc.) and send them to SSRS reports, a kind of special reporting. Thus, we created projects with more than 125 web pages and more than 150 reports in less than one year, which is quite a significant achievement, given the small workforce.
