The first application was extremely tricky, getting used to the feel of the gel etc. Further applications became much easier & I think that I have now cracked it. The major issues I have are with the sizing. The 2 lager sizes only have one pair of each yet there are very tiny sizes (chid sizes) which have 2 pairs of each. At present only 2 of my fingernails are covered completely (even allowing for a couple of mm gap) & only 3 on my toes are properly covered. I do love the product but was slightly put off by the Subscription aspect. I hope that I will be able to order on a ‘one off’ scenario in future as I only wear nails for special occasions.
