Several reviews point to ongoing issues with slow support replies and licence activation. More than one user says tools like SafeErase and the defragmenter are confusing or don’t work as expected. One long-term user describes the software as stable and easy to use, standing out against the negative experiences.
Examples from available reviews (Nov 2021 – Mar 2026).
Long-time customer experienced failing features and poor helpdesk support.
“It is the worst service from a helpdesk that I have had”
Wiping tool caused system failure and left PC unusable requiring repair.
“they hijacked my pc”
License shows over-activation and support access requires a valid license.
“it says I have activated it on too many computers”
Long-term user praises product quality, ease of use and reliable support.
“The software works seamlessly and flawlessly, and is very easy to use.”
Slow or unresponsive support comes up repeatedly. Several users describe helpdesk replies as unhelpful or defensive. Some also say support access is blocked by licence checks, which makes it harder to fix problems.
Only a small number of reviews mention pricing or the licence model. One reviewer specifically said the defragger is overpriced. Most comments focus on how the software works and the quality of support, not cost.
Users describe SafeErase and the defragmenter as confusing to navigate and ineffective to use. Several accounts call the recovery and setup steps poor. Reviewers tie these usability problems to the failures they experienced.
One review describes a serious reliability issue in which a wiping tool reportedly left a PC unusable. By contrast, a long-term user says the software runs smoothly and reliably. That positive account is outweighed by multiple reports of failures.
Reviewers describe support messages as defensive or not useful. More than one review directly criticises the helpdesk. Some users also report that licence rules prevent them from getting further help.
Most reviews focus on problems with support, licensing, and tool reliability. One long-term positive review offers a very different experience, suggesting sharply mixed outcomes. Overall, there are more reports of service and reliability issues than confirmations of steady performance.
For each review, the core experience based on original source reviews.

I've been a user of O&O products for over 2 years, and I have been thrilled with the quality of their products! I've used O&O's backup software on several PCs, and it has saved me from THOUSANDS of dollars in lost information. The software works seamlessly and flawlessly, and is very easy to use.Thanks a million times for the support you have always given me when I have a concern. I don't know what I could do without your O&O Browser Privacy and O&O Auto Backup systems. I no longer have to fear the safety of my data, privacy as well as loss of information. The items are of good quality, easy to maintain and worthy of the prices.
