Whos used Proshells or Extentubes??

hey.. i dont have too much experience with extensions or anything but i did try the proshells and they were very noticeable in my blonde hair .. the color of the proshells and my hair didnt match well enough, was mainly the problem, and since there are only 3 colors to choose from , black, brown and blonde i decided to opt for the shrinkies.. theyre clear so you dont really notice them if they peek out.. the proshells do seem non-damaging though and they were pretty easy to put in and take out
