“I would recommend this to anyone. It was a cost-effective solution to my ampoule opening needs.”

Lexie S., Oakland, CA (Purchased: AO DIN 1 ml unit)

“The unit is still performing excellently. I am allergic to lidocaine; so, the opener has been used numerous times and been used as a front-line device to ensure safety for both cuts and chemical exposure. I am extremely pleased with both the performance of the device and the customer service received. Couldn’t ask for more. Our staff report no failures and easy to use. Thank you for a quality product!”

Tammy M., Clinical Nursing Supervisor, Trigg County Hospital, Cadiz, KY (Purchased: AO+: custom HOSL 2 ml single base unit with needle holder)

“It works great. Far better than opening by hand!”

Nate S., Buda, TX (Purchased AO DIN 1 ml unit)

“We have used daily up to 25 times. Works like a champ. No issues. Other staff use as well and no injuries at all. Great product, very convenient to use. I had worked in Emergency Room for 3 years and never saw this opener before, wished they’d had it there.”

Paras P., RN, Sheridan College Health Services, Brampton, ON, Canada (Purchase multiple AO DIN 1 ml units)

“I am very happy with my purchase. My 5 ml ampoules open without any difficulty, just like in the videos on your site.

Nice to see 3d design and printing being used innovatively to make things safer.”

Anonymous, Kamloops, BC, Canada ( Purchased: AO+, 5 ml double post with needle holder)
