on 3/29/16, I had a fabulous experience with a nice and very knowledgeable gentkeman, his name: Nathan! I'm pleased say he knows his stuff when it comes to the O pens, concentrates. Hands down one of THE BEST Bud associate's EVER! He never rushed me, very patient with in all my questions. I truly hope I get Nathan again!! Please recognize him for a fantastic job well done! He definitely is an asset to your company! I love the concentrates, I bought the K.I.N.D clear Atomizer. Totally love the night one, I now can sleep 6 hours straight at night. Thank You!!!!
