I wouldn't suggest paying for the full version unless you've tried out the free version first and like it. Recommended if you don't mind the limitations of the free version, (watermark + 10 minute limit). While it doesn't have the same kind of customization as a software such as OBS, it certainly does the job. I believe it is still a one time payment, and it is worth it if you're looking for an easy to use recording software. The full paid version contains enough features to record your screen well, as well as webcam, HDMI devices and game capture cards. You also should be aware that if you do not pay for the full version, your videos will have a Bandicam watermark, and you will be limited to 10 minutes of recording time per recording. 'Bandicam Company' also provides Capture Library (Bandicam SDK) and Video Library/SDK which are used in major game companies such as Nexon, Tencent, Ubisoft etc.

I've been using Bandicam for many years to record my YouTube content, and I can say with certainty that it is not the best screen recorder available, but it is good as a beginners stepping stone. Bandicut Video Cutter is super-fast video cutting software which allows users to trim parts of video quickly while keeping the original video quality. Average screen recorder, but there are better.
