David Lantz: "Thank you, this is by far the simplest, and most friendly utility for building db record system I have ever used. I wish I could get my systems guys at the office to purchase this for our company would be so very helpful and speed up a lot of work. I for one have used it for everything from a simple inventory record of my house, to a members record for my church just little pet projects and a test bed to test my own db builds and theories before having to hand code at the office..... it is a lot of fun to work with".
Philipp Gerber: "

The product is so easy and super built that you can achieve visible and great success after a short time. Also very much possible with the product. A class product. I'm already looking forward to the next versions and extensions. Keep it up.

Support to the product is just perfect. Each Support request is quickly and very competent solved. Also various assistance, which does not fall into a support, are also perfectly processed. There is a direct wire to the manufacturer / developer and this is notth. Thanks for the class Support".
