Straightforward transactions. They have what I want and it arrives promptly every time.

After being told it was being shipped, my order was cancelled. When I emailed to ask why, I was told it was because I was overseas. This was the case, but both my billing and shipping addresses were in the US, so I don´t see why there should have been any problem.

The product I ordered was back ordered. Gustavo Martinez contacted me personally to help me get what I needed. He called multiple suppliers to see if he could get the product in pieces instead. In the end her helped me figure out that I didnt even order the correct product for my application and got the correct one ordered for me. By far the best customer service I have ever had from an online order!

We were able to find what we needed at a reasonable price. Checkout was relatively easy as well. After ordering, we got a notification that the items we ordered were on backorder. It would've been nice to have that inventory be accurate on the website before placing the order, but I understand things happen. We were given the option to cancel, but since we needed those particular items in no huge rush, decided to keep it in place. We received one shipment of the ear protection, but I believe the remaining maintenance kits are still on backorder. I hope we receive them soon. Other than the discrepancy in inventory and the wait for the two shipments, things went well. When we need more PPE, we'll likely shop with them again.

Reply from www.envirosafetyproducts.com

Thank you for your feedback. We’re sorry for the frustration this caused. We want to clarify that your order was for one child-size cervical collar, which is what was shipped. The product photo shows both the adult and child models so customers can see the size differences, but each is sold separately.

Our team reached out by phone and email to explain this and offer you the adult size free of charge, but we regret that it left you feeling dissatisfied. If you’d like to discuss further, our management team would be happy to assist. Please contact us at: (800) 637-6606

Always great service

The website said 1 day when ordering, the reason we purchased from you. It's been 14 days and we still don't have it. The other issue is you were not the lowest priced. I called customer service and they answered my questions but did not seem concerned at all. Actually I remember hearing a snicker or light laugh.
