I will be truthful here. The product itself does deserve 5 stars.
This issues I have is amazon sell 100 for £9.50 but I wanted free postage and found these. I will admit I should have read the description that is only my fault but to think I paid £10.50 for 25 and I could have had 100 for £9.50 plus p&p. will read description from now on that for sure.
But if you need to clean your sensor on your camera like I did and value for money no issue. Then these are fantastic. If you want better value for money shop around.
