I agree, but as an aid for us newbies to gain the confidence and dexterity to complete a successful re-coil and re-wick, I think they are great. Just completed my first re-build of an Ego EE2 ( with my large sausage fingers it was no mean feat! ) manipulating the, almost invisible, wire ends into their respective place was a bit of a challenge, so was glad of having one less part of the process to fiddle with. Took about 5 mins to get the new coil and wick in place. Popped it on the Vamo to check it and got a reading of 2.2ohm, so am feeling well chuffed with myself. Will progress to making my own coils and wicks as my confidence and dexterity improve. Surely anything that encourages, is a good thing? They are not by any means over priced either.
