Stay FAR away from these Chem Lab ********!

I had a terrible experience with this Chem Lab Supplies. Their website's payment checkout was not active, and I had to contact them for a manual invoice and do EFT instead of the payment options they provided on the site. Not to mention that the price they invoiced me for was higher than what was on the website! I had to phone days later to confirm if payment was received and if my package was shipped. It turned out that they didn't have my address due & if I never called, they'd never have shipped my product. When the package finally arrived, it was half of what I ordered but they wrote the weight I ordered on the product label… I have a scale & it was clearly less so I weighed it and sent them a video. They sent the other half BUT I never asked for that, they just did what they wanted. And then later when I tested the purity of the chemical I ordered, the results were inconclusive—either the product was **** or the diluted to next to nothing!!! When I sent them an email about this, requesting a refund, they never responded. I would strongly advise people to stay away from this supplier. They are clearly ********!
