Worked out great!
Received when promised, came with instructions and pipettes and, most importantly, all live Planaria! It wasn't clear that the purchase came with instructions and pipettes other than another commenter suggested such so we were not sure until the package arrived. We learned quickly not to leave them in bright light. Worked out to be great science fair projects.

Excellent regeneration results
I use these planaria for a regeneration lab in my 7th grade life science class. We make only one transverse cut to create a head and a tail. Survival rate is excellent. (In the past, I tried multiple cuts per specimen with little success.) Most specimens fully regenerate in 3 weeks.

Students love this!
These planaria are great for teaching regeneration and my students love it! Just a few tips that I learned: keep them in a fairly warm place (one year they got too cold and died); feed them a little piece of egg yolk once per week, but make sure to clean their water after letting them feed for about 30 minutes; only cut them into two pieces and don't cut through the head region; observe them under dissecting scope; make sure to use pond/spring water as tap water will kill them!
Otherwise, these regenerate fairly quickly and are fun to watch!

I am mentoring three high school students for a science project. We are testing the environmental factors on the growth and behavior of planarian. The first batch of planarian were frozen to death due to the extreme cold weather we had recently. The company was very kind to send a replacement batch free of charge. The planarian are healthy. The experiment is still on going. We are hoping some interesting outcomes.
