User Reviews

User reviews are mixed. The app is praised as good, very useful, and even the best for USB/pendrive use, with some endorsements. However, reliability is a major issue: many users report it does not work or fails to detect USB/SD cards, and some cannot open it on various devices. Ad load and frequent updates are common complaints, and a few reviewers warn about privacy risks when the app requests file access. Overall, it shows potential as a USB checker but suffers from inconsistent performance and nuisance ads/privacy concerns.

Pros

Some users report it works with USB devices/pendrives when others do not.

Cons

Reliability issues: many reviews say it does not work or fails to detect USB/SD cards.
Ad-heavy experience with many ads and updates.
Privacy and safety concerns about reading or potentially deleting files.
Inconsistent behavior across devices and some reviews say it does not open.
