Review on Powsure Tempered Children Underwater Snorkeling by Steven Ali

Bought for a snorkeling trip to Hawaii for our 4 year old son. When testing in a pool, I found the snorkel tube was leaking and quickly filling with water. I tested it myself after seeing my son having trouble getting water down the tube (just to make sure it wasn't his mouth seal or some other stupid thing) and confirmed there was a major leak. I've tried resetting the seals but nothing I've tried has been able to stop the flow. We ended up using a mask and a trusty adult snorkel for snorkeling in Hawaii. I swapped out a replacement on my return - and to my surprise, the replacement leaked the same way. This was annoying and could be downright dangerous considering the target users are children. I go with another brand.
