I have a Cyber Aqualand and like it a lot. One thing you have to remember, it is not a full fledged dive computer. However, you will find it easy to use to track your dives, depth, time, temp, surface interval........ etc... It is reasonably accurate and agrees well with my computer. The ascent feature is nice. Beeps when you exceed the settings.
The software is rudimentary but works. You can even put some pictures in the log.
Don't throw out your tables yet if you don't use a computer too. Read the instructions well. It will make things a lot easier. Once you get the hang of it, it's a breeze.
