The quality of the daphnia we received was very poor. I ordered 6 bags and there was barley enough to cover 1 class. I have had to order more from Blades but we will probably have to cancel some classes this week as we don't have enough.
Hearts were in good quality for practical activities. It was treated well to have the main blood vessels preserved, great for learning.
used this product before, good quality, very reliable, works every time
definitely worth to buy.
Darwin are very reliable and always deliver excellent products.
