Terrible user interface and too pricey. You get tricked into installing everything than you have yo pay to use it. I highly encourage against using this software.

I was having a late night transferring programs from on pc to another. Could not find license info but I had the receipt. Emailed customer support and was assisted very promptly and professionally. Thank you!
Application was perfect but for me it was one time use
Application was perfect but for me it was one time use. Problem was that your mails went to spam so i was frightened that my card was stolen, I appriciate your understanding and will to resolve my problem, and if I need again your application I ll be more than willing to give you my thrust again
My experience was great because Sean was able help me solve a difficult problem. Also, response was very good...usually within hours which okay for my situation.
Hi Sean,
So great to receive your advice, information and assistance in my recent communication with you.
You handled the matter with common sense and every day genuine language and in a simple format which allowed myself to proceed with the the information you provided and once I loaded that into your product, everything is working perfectly.
Some folk over complicate matters with getting away from everyday common sense advice etc.
Once again many thanks for your assistance.
Enjoy a great Festive Season.
Best wishes Des Stevens.
I purchased a program that I use for transferring folders and SMS from my MB phone to my laptop. Unfortunately, I got some problems with the installation on my new laptop. After contacting Coolmuster I received very quick, friendly and helpful service information on how to fix the problem. Excellent services.
I needed to cancel my subscription because I didn't require the software anymore. I couldn't log into the site no matter how I tried, but Annie took care of everything for me. Great service, prompt and efficient. Thank you so much!
I purchased the CoolMuster Android Assistant primarily to back up my text messages. Upon purchase, I found it easy to use, intuitive, and comprehensive...except that it only exported the received side of conversations. I definitely needed the Sent side as well, so contacted Customer Service. Sean was very helpful, advising that the Coolmuster tool was not fully functional with Android's Advanced Messaging feature. He recommended a workaround, but that would not help with historical conversations. Since the primary reason for purchase was not possible, I requested a refund and Sean provided it immediately and without fuss. He was informative, helpful, and a pleasure to work with. I will keep my eye on the Coolmuster Android Assistant product, and when upgrades are made that address the Advanced Messaging limitations, I will certainly be inclined to revisit it.
Total scam. Didn't do what it said it would do. Extract contacts from broken phone. Said I had the rights to cancel within 14 days then refused to let me cancel. I'm gutted

I tried to contact the company in February 2022 about a problem that I can't solve. It is already the end of April and they still have not gotten back to me. I also wanted to discontinue the subscription minutes after I downloaded and installed it but nobody has gotten back to me as well.
