Fast and reliable UltraDefrag does everything I want it to do - and more. It is fast, reliable and stable I can only reecommend it.

Very good software Since it was open source has been the best defragmenter. It's also usable as a portable software. Now it's a commercial software, but nothing has changed.

Absolutely no customer support Absolutely no customer support. Even Fastspring screwed up by sending me a blank URL for the download. None of my many emails to you, Fastspring, and Dimtri were responded too. In my research I discovered that this same scenario happened in 2020 when I first bought the product. It took until three months until November to get the product. I do not plan to upgrade in the future due to these two scenario that left me very angry.

You guys are 2 paranoid about pirating You guys are 2 paranoid about pirating; it would be nice to get an install copy so when I format my SSD (as I occasionally do); I won't have to beg borrow or steal?

Over the past few years Over the past few years, I tested a variety of defrag software, some of which are among the big names in the industry. There is an analysis tool available in Ultimate Defrag which gives a numerical value of the degree to which a defrag job has optimized a hard drive. So far, and among a whole variety of software I gave a try, Ultra Defrag achieved the highest score after a full boot-time optimization (with file arrangement based on time of access in ascending order while keeping the other default settings), which was easily noticeable in the speed of file and application opening as well. The same excellent performance can be maintained by periodic quick optimizations after a full boot-time job, which can be scheduled as an automatic defrag.
