Document: worked great no leaks easy to put on, going to order one for my husband for when  we take vacation
the masks were broken when i recieved them. one even had a clip holding it together qhich means it was shipped broken. the letters on the fins are smudging off. i am going to try the fins at the pool and if they dont work i am going to ask for a full refund. If not I might consider buying masks at walmart or something. Either way DO NOT BUY these. worst experience Ive had with a seller so far. I was so excited when I got them too.
nice set good product
a good product very durable, I would buy this product again with your eyes closed, a boon for SCUBA diving
While test fitting this equipment in the hotel room first the mask of one set broke where the strap attaches to the mask. Then the similar connection where the fin strap connects broke on the other set. Between the two sets we have one functional set of equipment and one of us has to sit on the beach. Damn. This is why I bought new stuff so this would not happen. I am a mechanical engineer and a designer of plastic parts.
When the other one arrived, the flippers were HUGE!!! They were 23.5" long from heel to tip of the flipper. That was way more than I needed, so I returned those, and took another chance on these. I just got them unboxed, and checked them over. The screen printing is not smearing like last time, I also tried on the mask and the flippers, and they feel to be good quality.
We took them to the Bahamas. The bags they came in made it very easy to transport and keep track of. They fit great to help vein fun, easy and safe!
Very fast shipping. Item was exactly as described. Fins and snorkel work great, the only knock against this kit is the mask. Overall it is a very good mask, but the little pins that hold the straps on break very easily. They are made out of plastic, but so are the ones on the fins and no problems with them. At the price, though they are a good value. Just be easy on the mask.
US. Dive set as expected. Excellent product. This set was purchased as a gift for my brother based on his love of the set we purchased for my husband. Great fit.
This Snorkel kit is so very useful to me especially when we go to the beach with my relatives. Thanks Amazon..
