Reviewers view the EP 128 GB as a solid budget choice with decent sequential speeds and 4K capability, though they note the absence of A2 performance and endurance rating compared to higher-priced rivals.
Users generally praise the smooth app performance and 4K support, but some report premature failures and permanent write-protection problems.

Professional reviewers note that the Canvas Select Plus (especially the SDCS3 version) delivers a solid 150 MB/s read/write performance, A1 app class and V30 video class, making it a reliable choice for Android devices and 4K recording. They commend its durability and lifetime warranty, but point out the lack of an A2 rating and the lingering presence of the slower SDCS2 variant, which can confuse consumers.
Everyday users appreciate the card's reliability, fast app loading, and rugged build, often highlighting its value for money and plug-and-play convenience. Recurring complaints focus on receiving the slower SDCS2 version when expecting higher speeds and occasional 4K video hiccups, as well as unclear packaging that doesn't distinguish the two models.
