We received multiple broken bottles in our shipment. Packaging can be significantly improved. Product works great and serves the purpose of helping protect against parasites.

I chose this because it was purported to cause less sting to the animal. Success in that department. This was important because I was using this for mites and would need to inject again in 2 weeks. My animal had no flinch when administering. It seems to be working on eliminating the mites. My only suggested improvement is the size of the bottle. I wish there was a smaller bottle option.
