Thank you very much. Customer satisfaction is #1 for me. ranked #10 out of 325 sellers with 99.8% positive feedback from 423 transactions That is my feedback. If you go thru my entire feedback, you will see it is all 5 out of 5. The only reason my score is even a 99.8% (which i hate) , is because i like to give newbies a try.. A couple of newbies didn't know you're supposed to leave a 5 out of 5 on early finalization and left 3's saying they would update once receieved, and forgot to update their feedback. Also all of those transactions are real orders. Real product, real packaging , real shipping and real delivering. None of that bullshit "lotto entry" feedback boosters. My rep means the world to me, and i stand behind my products. I would not sell anything that i would not consider the best of the best. Please update once you have tried, and if you have a reagent testing kit, i would encourage you to test my product too because it will pass with flying colors. Cheers.
