Journal of Systems Engineering and Electronics

I would like to briefly share my personal experience of submitting papers for reference:
Submitted on 16th March 22, and it was received and sent for review on the same day.
On 17th August 22, it showed that the reviewers had finished reviewing. During this period, there was no display of the review progress. I only saw that the editor had sent it to 5-8 reviewers. After reminding once, they said it was being reviewed, so I had to wait.
Rejected on 6th September 22. The opinions of the two reviewers are as follows:
Reviewer 1: The overall structure of the paper is good. The description of the basic knowledge section is redundant. The experimental and analytical parts of the manuscript lack clear control groups or other comparison indicators. Rejected. (Very vague opinion, did not point out where and what kind of control experiments and indicators are missing, not helpful for improving the paper, and also doubted whether the reviewer understood the author's experimental content)
Reviewer 2: The organization of the introduction is confusing, and the author should reorganize this part. The motivation and contribution of this work should be clarified and emphasized. Try to set the issues discussed in this paper more clearly and write a paragraph to define the problem. No decision on accepting/rejecting the manuscript was given. (Obviously, they didn't read my experiment and directly rejected it after reading the abstract and introduction)
In short, it took half a year for this journey, and what I got was two vague review opinions plus an editor's rejection. The experience was very bad. The email did not mention the possibility of appeal, so I assume that there is no way to appeal, and I am too lazy to argue with such reviewers.
I will not submit to this journal in the future.

Before, when I submitted, it would be very quick. After submitting the revisions, it took about a month to be accepted. After submitting the publication fee, I received the acceptance letter within approximately a month (specific time is not clear). Several months later, the manuscript was proofread. It was published in the first quarter of this year, which took 3 to 4 months from submission to acceptance and one year from acceptance to publication. It can be considered relatively fast in terms of speed within the field of SCI.
