I have been an Animas customer for 7-1/2 years. During that time I feel the customer service has generally been outstanding. My pump order was processed quickly and efficiently. I had my pump in less than two week from the time my doctor sent them the script.
I've had three instances where I needed to contact technical support. Once was after normal business hours and I had to leave a message. I had a return call from a support person in less than 30 minutes. The most recent contact with technical support was this past Friday. The screen on my Animas Ping has dimmed a bit and is getting a little difficult to read. I called and was speaking with someone in just a couple minutes. She determined my pump was still under warranty and within 15 minutes had processed to send me a replacement pump overnight.
About a year ago Animas had instituted a new supplies processing system. That did create major headaches for both Animas and customers causing poor response times, late or incorrect shipments, etc. My last couple orders have gone through quickly and with no problems.
Basically, Animas is not perfect but no one is. I believe they do an excellent job.
