Review on Panasonic RP SDUC64GAK Ultra Speed Class 3 by Michael Sheldon

As an IT professional, I purchased this SD card hoping to improve my printer's performance. Unfortunately the claim of ultra-speed class 3 is far from the TRUTH .It didn't make much of a difference in printing. However, it did work well in transferring files from my computer to other devices. The cons of this product outweigh the pros, especially if you're looking to enhance your printer's speed..
