China: Fujian Newland, Shenzhen Tongcai Toncy, Taiwan Unitech and so on.
Europe and the United States: logic, moto, intermec, datalogic, honeywell, etc.
Japan and South Korea: Casio, Denso, M3, Bluebird, etc.
The quality of European and American brands is good, but ** is too high.
Japanese and Korean brands have a good appearance, average quality, and high quality.
Chinese brands have a lot of stamina, cost-effective, better and more timely after-sales service, and the market share of foreign brands in China is getting smaller and smaller, and the market share is getting lower and lower.
Shenzhen Tongcai toncy's handheld terminal products have good performance, high quality and low quality, which is worth recommending.

There are no requirements for domestic production and import, right? Generally, the more commonly used ones are Xinji and Motorola. Of course, these 2 brands are still very good in terms of quality and cost performance. I don't know what you have to ask for, I can recommend a few models for you.

Our company's products are also good, the certificates are complete, the product quality is also very good, you can use samples for free.

Generally use the choice of domestic good, almost more than two thousand, such as industrial use for explosion-proof, dust-proof, anti-drop and other requirements for the use of imported data collectors almost three or four thousand or more - Fuzhou Shangchen barcode.

There are many brands of handheld data collectors, such as Honeywell, Motorola, etc., which are relatively famous, and of course, ** is also relatively expensive;
The more famous one in China is Dongda Integration, which is widely used in logistics, retail, and manufacturing. As for the many other domestic brands, I won't list them one by one, you can learn more.
In short, the domestic one is cost-effective, functional, easy to develop and use, low maintenance cost, and short maintenance cycle;
The imported ** will be a little higher, and the corresponding function development cost will also be high, and the maintenance cost is high, and the maintenance cycle is longer.
You can choose the right product based on your project needs, budget, and workload.

The amount of usage is determined.

To put it bluntly, collectors don't work well. Because this tool is a professional tool, not the kind of popular software, so, you need to have a certain foundation, such as: at least know how to view the source of the web page**, hehe.
There are some visual collectors on the market, but there are very few data that can be applied to this collector, after all, the requirements and structure of collection are changeable, and sometimes they are very complex.
If you look at it from the scope of the collector, I suggest that you should clarify your needs, what type of data you want to collect, mostly articles, or structured ** data, whether you need to log in to collect, whether there is a problem of post submission, whether the collected data is directly published, or stored in the database for secondary processing, and then published or analyzed.
If you are collecting information from forums, blogs, and articles, it is recommended to consider madmen, threesomes, and locomotives.
If you are collecting structured data, you can consider network miners, locomotives, and network spirits.
If you focus on data processing, you can consider network miners, which are very powerful in processing data collection, and are very suitable for non-technical personnel.
In terms of ease of use, the locomotive is more complicated, but the function is also very strong, but I always feel that there are many functions, and they are not particularly useful.
The use of the network is also simple, but its ** is more expensive.
The network miner is a little easier to use than the above, and the functions are more practical, but because it has just been launched, the stability is not particularly good.
It's up to you to choose.

According to your description, this is a very special next page button, the next page link or button on the vast majority of web pages, the octopus collector can automatically identify and automatically add the next page loop, but there are very few special cases, you are this kind of, in this case, it is not difficult to deal with, but it is not possible to generate the collection process automatically, and it is necessary to drag the process slightly semi-automatically manually: I consulted the Octopus forum for specific operation methods, Here's an excerpt of the solution from the Octopus forum reply: >>>More
The locomotive collector is a copying tool: after writing down the corresponding rules, you can quickly collect a large amount of content from others in a short period of time, and then publish it to your own **, to put it bluntly, it is stealing
