This question requires my subjective judgment, so I will provide a personal opinion based on my personal experience and understanding.

I don’t understand Jinsoft Software and cannot comment on its specific usage experience. However, from the perspective of the carton industry, a useful software should have the following characteristics:

1. Complete functions: A useful carton software should be able to meet the needs of the industry, including Functions in design, quotation, production and other aspects.

2. Easy to use: The software operation interface should be simple and clear, easy to use, and does not require too much professional technical knowledge.

3. Strong stability: The software should run stably without frequent crashes or lags.

4. Technical support: Software developers should provide complete technical support and promptly solve problems encountered by users when using the software.

So, if Jinsoft software has the above characteristics, it should be considered a useful software in the carton industry. Of course, the specific needs of each enterprise are different, and the evaluation of software will also be different, so the answer to this question is also somewhat subjective.
