I'm a professional computer tech with my own concierge business. I've researched plenty of similar software. Yours is the best in the world! I basically gave up on trying to switch my HDD to GPT without formatting it. I found AOMEI partition assistant and switched it in seconds without deleting all my stuff! Keep up the great work.

Hi, I’ve been building PCs with Windows/Unix/NeXTstep since 1987.Your partition Assistant is AWESOME! I restored a 256GB SSD backup to a new 512GB SSD and got the dreaded “unallocated partition not next to active partition” issue. Your Partition Assistant fixed it in like 15 seconds, and that time is with me choosing the options! You guys are the best! Thanks!

I needed to merge two partitions but the OS was at the end of the disk (pretty much impossible job) with this tool 5 minutes BOOM done it easyI am more inclined to purchase from #AOMEI and recommend your brand. I like your business model.
