Handy if you need a set of USB boot sticks to carry around. Most ISOs are around 1-2Gb so you don't need any bigger.
Have used these for ages and found them both reliable and reasonably fast to boot. Bonus is they come in three distinctive colours so you its easier to remember which is which.
Out of stock online but the website showed stock in all our local shops. Though I did get the last pack from the nearest one.
