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

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.

I had a question about the products and was answered quickly and professionally. It was a great experience and look forward to doing more business with you.

David Verified Customer

Customer care was great. The individual I spoke with regarding a delayed shipment kept me informed over a period of five days. He called me to let me know the reason for the delay, when the item would be shipped and when the item had shipped. The lack of transparency at checkout was a deal breaker. If you charge a customer almost $15 for 2-day shipping then it should not take a week to get the product to the customer. If it takes that long, the company broke the contract.

Easy to find what I needed. I will use enviro safety again.
