Magula Liquid Nitrogen Container Cryogenic Container

I used this for a class I taught the first week of December and by the end of January it still has liquid nitrogen in it - wow, 2 months (and counting) - I wasn't expecting such good quality from a lesser expensive Dewer, but I am very impressed and satisfied!

Would have given 0 stars, but that was not an option. I never received the product due to a number of screw ups!!! According to amazon when placing the order it was supposed to be a 2 day arrival. But with no notification from amazon for days, I kept getting a message when I checked the tracking information that the package was stuck in Kentucky. If I hadn't spent many hours on the phone I never would have been able to figure out what was going on. Amazon representatives kept giving me false information. The next thing I know after all the phone calls I get a message that my package will be delayed for 2 weeks!!!! Amazon (or the Magula company) decided to change "carriers" to UPS. UPS gave them a tracking number which was invalid. When dealing with frozen semen a person cannot wait for 2 weeks extra!!! I stand to loose $5000 in semen!!! Not sure if the Magula company just screwed up and couldn't live up to the promised delivery date of 2 days. But I will not be ordering from this company again!!! And I am cancelling my amazon prime!!! It was worthless!!! Neither amazon nor the Magula company sent me a delivery delay notice or even an apology.

Buen producto!
