My first DIY order was placed with Wizard Labs and I was satisfied 100% with every aspect of the order.  It was packed well, priced good, had a decent selection, had almost everything I was looking for in once place, and I felt they were a reliable source due to what I had read about them.  Now, on to the reason I made this post beyond the typical "thay wurk reel guud" comment.  I had a series of questions about several of the products I purchased and the quick, thorough, and extremely detailed responses I received blew me away.  Unless they do not carry an item or there is a major difference in price I just order it from WL now.  Unless something changes this will remain my go to for DIY needs.  
I will also add that there nic has a decent throat hit for those that like that.  I ordered 100mg/ml in VG.  I prefer a smooth vape but it was still vapable for me.  I am still on the search for a smoother nic, preferably clear and in VG base although I am flexible on both.  If anyone can point me to a nic source with such traits I would be quite grateful!  
This concludes my opinions and experiences on Wizard Labs and hopefully everyone else has found a vendor they are happy with.
