“I have used these refills for 4 years with no issues but the last couple of months I have noticed some of them do not scew onto the battery. At first I thought it was a one of but there's at least one in every packet of 4 that is defective. The last packed I opened 2 out of 4 didn't fit so had to throw away. They are not cheap so very disappointed.”
“Much better quality product than what you can buy from the shops, can be hit and miss and times as have brought from shops and found them to be faulty but the product is always of good standard.”
