Thank you soo much Tifanny for this post. I have to choose a DE and I have honestly been so confused. The clinic I am visiting for this procedure has above 100+ DE and I have no idea which one to opt for. This post of yours is so informative. I made a list of things you have mentioned in your post. I will be cross-checking this with the database. The forums can sometimes prove to be so helpful. Thank you once again.
