I got a box of these dishwasher tablets last week to try as I always use the crystale rinse aid so thought I'd give them a try. I've used them 4 times in the last week with the rinse aid and much prefer them to fairy and finish. My glasses come out spotless where as before when I used the fairy ones my glasses used to come out looking a bit foggy even with the rinse aid. Would definatley recommend them and I've been back to Poundland today to buy some more. 18 tablets for £1.00. Excellent value.
