Reviews show a split experience: a long‑term user praises backup reliability, while most recent reviewers report support, licence and functionality problems. Several customers describe activation or helpdesk barriers and unclear responses when features fail. Multiple reports raise concerns about certain tools’ behaviour and the pricing/licence renewal model. Prospective buyers should test tools in a non‑critical environment, verify licence sellers before purchase and keep records when contacting support.

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.
