I'm using the many software products from the Coolmuster since 2023. Found that those software's were very user friendly, simple and easy to be used by nontechnical persons.
Also, their Support Team responses are quick, and easily directive.
I'm mainly using those softwires, especially the freely giveaways to test.

Customer service was very good. Simplified instructions and prompt response. I was unable to make the product work and in spite of all the suggestions kept getting the "Turn on the debug" option which was on but not responding. The customer support was excellent and helped me back up my android wirelessly. Very good response time with simplified instructions.

Android assistant software doesn't work well at all. In fact, I eventually ended up using the FREE Google Backup that was on the phone backing up regularly to get my new phone back up & running with all of my apps, wallpaper, configuration and so on. Android assistant couldn't complete much of this or left me with partial restore. Will never use this product again simply because it's not complete.
Reply from Coolmuster2026-06-25
Hi, Independent_forever,
Thanks for your feedback.
Just to clarify, Coolmuster Android Assistant can only restore the data it has previously backed up (such as contacts, SMS, call logs, photos, videos, music, and more). It does not restore system settings, wallpapers, or installed apps like Google’s native backup. About the details, you can check here: https://www.coolmuster.com/android-assistant.html
We understand this difference may have caused confusion, and we appreciate you sharing your experience. Your feedback has been noted as we continue improving clarity and user guidance.
Yours Sincerely,

After purchase of Backup Manager I found that some app apks wouldn't restore. I therefore contacted support. The response was very quick, but following unsuccessful command line attempts to get the restore function to work it was agreed that a full refund would be provided. As promised this was credited to my account in a couple of days. Sean was very helpful and efficient and so, if the software works for others, I have no problem recommending this company. It didn't work for me but I didn't lose out.

I had an automatic renawal partly due to my own tardiness in cancelling my subscription (cancel because no longer needed, not a bad experience or anything like that). When I let the support know that I actually wanted to cancel and not renew they immediatly took care of it for me. Top service, thanks!

Im 62yr old technology deficient female, was able to download texts in two different formats, only THANKS to timely reply from customer support, so that a client could have "every message" between me and one of her tenants (7yrs worth) and its relevant to her needs. Now she can actually print it all out if needed and I did not need "share" message by message off phone. THANK YOU. I have trust issues, didnt trust this at all, researched and decided do it. I hope never to regret that of course, LOL, but so hopeful will be useful tool. Wish I took the LIFE option instead of one year.

Hi, Dani,
Thank you so much for your kind and thoughtful review!
We're truly honored to hear that even with a self-described “technology-deficient” background, you were able to successfully retrieve 7 years' worth of important messages—and right when it mattered. We’re also glad our customer support could assist you in time and build some trust in the process.
Your feedback means a lot to us, and we’re thrilled you’re finding the tool useful. If you ever decide to upgrade to the lifetime option later, feel free to reach out—we’d be happy to help. Thanks again for taking the leap and trusting us!
Yours Sincerely,
