Rated 5 out of 5 by from Inexpensive great toy! My 3 year old loves this toy!! He doesn't have a lot of bath time toys but this is one of his favorites. He winds it up or I do and we play for what seems like hours. It continously floats in the tub the whole time, unlike most toys that float for a while then sink. Just take a look at the photos. The mesh like (flexible) holes throughout the tubmarine toy make for easy water drainage and prohibit that easy mold buildup. The green periscope is lightweight but allows the toy to float, there are no choking hazards which I like. This should last for years to come and will be great in the pool in the summer! So if you want a decent, inexpensive, busy water toy for your kid then this is the way to go!!!

Rated 5 out of 5 by from Tub-marine Fun I have searched and purchased numerous bath toys...Specifically toys that will hold my 1 year olds attention, so he won't try to jump out of the tub. I am so glad that we found this product by O-ball. With the finger holes, it is very easy for my son to hold onto. He can also grip and hold the top green part, as well as, winding up the tub-marine himself. This is seriously the cutest toy ever! My son loves it and it entertains him the whole time in the tub! I absolutely recommend this..the quality and design are noteworthy!

Rated 5 out of 5 by from Perfect for little hands! My 1 year old absolutely loves the tubmarine! He usually just plays with the soap bottles but not this time! It was easy for him to hold onto and for him to twist the propeller to watch it wonder around the tub. He plays with it even when it is not bath time. The little bit of water that was trapped in the toy easily drained out so when he was ready to play with it outside of the tub there were no worries about water dripping everywhere.

Rated 4 out of 5 by from Simple concept - big laughs When I received this a few weeks ago my 2 year old son immediately wanted to go take a bath. Considering it is usually takes sweat and tears to get him in the tub each night, I was already liking this tubmarine. Good: simple design and concept but once we got the hang of it he loved it - he even plays with it outside the tub. Not so good: you have to keep winding it and since the propellers are not that big it is a bit tedious.

Rated 3 out of 5 by from Bright colors and fun for bath I love that the toy is made of silicone and soft, but I wound it up forever several times (until I heard the clicking noise) and let it go in the bath and it didn't move like I imagined it to as it looks like a speedy submarine. My 15 month old daughter was amused though so that is what matters! This toy is made of high quality products and I am not worried that it will get mildew on it like most bath toys are prone to.

Rated 5 out of 5 by from Easy to use! After the submarine arrived in the mail I opened the package and showed my son. He jumped up and down with excitement and wanted to get in the bath at 3 in the afternoon. The submarine is gender neutral in the colors that are used. It couldn't be easier to wind up and actually works when placed underwater in the bathtub. My son now wants to get in the bath tub just to play with his submarine. He absolutely loves it.

Rated 4 out of 5 by from Fun little bath toy for 12m old At first I wasn't sure what was so special about this toy. It didn't look fancy or anything. But when i put it in the bathtub during bath time, my baby girl loved it. She liked the fact that it had propeller and float and was easy to hold. Toy is light and easy to clean as well:)

Rated 5 out of 5 by from Unique & Modern Bath Toy! I gave this to my Grandaughter for Christmas and got to see her playing with it in the tub. It's very unique and unlike most bath toys she has. The 'tubmarine' is submerged under the water and moves forward when you wind the green propeller. She had a blast with it!
