I have been using this for a couple of days now and here is my review based on what I have tested and seen so far. I am also benchmarking this against GSA E-mail Spider, which I also use.
1. The collection speed is pretty decent and definitely better than GSA, although relative to GSA, there is a major difference in the way it functions. GSA, filters emails while it collects them, i.e. removal of duplicates and you can add filters while you are processing, for e.g. while the emails are being collected, if I see an email with something like @yahoo.cn, I can simply right click and put this domain in filter so no more such emails are collected (I love this feature). I can do the same with a lot of other flters in GSA. With SEE, all the filtering/cleaning is done at the end so the initial numbers seem a lot higher, however, despite that I guess its fair to say SEE has much faster speed.
2. The keyword generator and url extractor, havent worked for me yet, in the 2 days that I have had it. I keep getting the "server busy" error.
3. The biggest problem is that the support is almost non-existent.
- I have contacted the author through every possible channel, i.e. the forum here, the in built contact tool, skype and the email id on the site and still dont have a response.
- There is no support community (which could help users learn, exchange ideas and maximise the use of the tool) which could actually substantially reduce the amount of time the author needs to spend on support as people could help each other.
- Once again, lack of support/response is a real annoying factor and I have to repeat myself on this.
4. It would be nice to have a "Pause" function too, for e.g. when I am taking my laptop from my home to office, I would like to pause the process. Also, a couple of times my computer went to sleep and the process stopped and never continued when It woke up, which means, I had no other option but to restart the process. After disabling the sleep mode, I let my laptop run overnight for collection and it was working fine, when I woke up in the morning, but eventually it got stuck at an email addrses (the program didnt freeze but the process wasnt moving forward) and nothing was happening thereafter so I had to terminate the process, so I never knew if the process was actually completed or not.
5. The other thing, I personally find annoying is that, each time, I have to manually save the search criteria as once you close the tool and re-open it, it defaults back to the default search critera. It would be nice to be able to "permanently save" our own search criteria.
Overall, I am enjoying the tool, but the lack of support is something that I feel is not allowing me to maximise the use of this software.
