Great product
Great for flightless fruit fly colony. We have dart frogs and this is a must for keeping them supplied with gnats

The Excelsior culture of choice.
This is my first bag of culture that I have bought, and I got it for the purpose of making fruit fly cultures to feed our frogs. The product arrived on time, and the packaging was undamaged. The product itself was tightly packed into a bag, and upon opening, I noticed that this was way more than I thought I needed. A small pinch of this substance fills a culture quite easily, and I expect this bag to last a long time. I have every intention from buying from this manufacturer again should I need a refill, but I do not anticipate that that will happen for a long time. Highly recommended for this purpose.

Great stuff works as intended.
Really happy. I have raised 3 new cultures in the last few weeks. Put in about 10 to 20 flies and you will have a colony in 10 to 14 days. Also smells good, which is helpful.

Well done?
Not really the product so much as the experience. This whole experience went professionally, and well. The product being the product, Iโm not sure there could be a bad one.

A ton of product
Huge amount despite the bag size. We have been using it for fruit fly cultures for months.

This stuff is all I use for my fly cultures
Buying fruit flies for my 3 dart frogs was getting to be more expensive than the dart frog setup was! Needed to start building my own cultures, and this material came highly recommended by a friend. They weren't wrong! Very lightweight, very easy for the flies to maneuver. The package will definitely make many, many cultures. Will buy again!

Fast Delivery - Good Product
This is a fairly simple product (Excelsior) to be used with fruit fly cultures. I was really impressed with how prompt the shipping and delivery of the item was, even during a time where there are noted shipping delays. The product itself was pretty much as advertised, there was plenty of media in the bag - much more than even what the picture showed so I really feel I got a good deal for my money. Very happy with the product. Would definitely recommend this product and this seller to others.
