It is fun. Used a bottle but seemed not to fit. I had to manually help it launch. Yes. I actually got down and had to push the bottle up so that it could launch. The the safest since the idea is that this lifts off like a rocket. Unless you find the right bottle, don't expect this to launch with the pull string. You get the right bottle than it works fine.

Bought as a gift but didn't fit into the first bottle it was tried on. I'm not sure if it ever fit on another.

It's a bit small and a little awkward to drink from.  The bottle seems solid though.  I've used it once...if I see anything else, I'll update my review.

Update: 10/28/15 - I've used it a few times now.  The opening is a bit small making drinking a bit awkward.  Dropping this to 3 stars.

Overall, fun product and I like that I can refill the bubble bottles. When bubbles are coming out, there are many and it's a blast. However, it can take a while to get going throughout use which is my primary complaint.

Love the idea and having fun things to use at parties. First try, couldn't figure out how much water to put in. They say to do 1/3 less for room for expansion, but if you fill them from the top hole, (ot sure how you can fill them any other way) you can't really see how much you are putting in. Also the water gets in the reserve wells around the circle molded area. When we took them out, they are mostly round, but not completely due to not filling them as full as probably should have, and they have a line going around the middle where the water was in the tray. Just not sure how to get the water ONLY in the circle mold. So I need to do it a few more times to get it figured out. I did use them and they do look really cool and fun in our drinks.

We were not super impressed with this item as it leaked in the middle despite various attempts. It was still fun to try and late enough in the night no one probably will care about the spills!

The floating ice chest worked well enough. Of the 12 I purchased, one had a large tear in the lid and could not be inflated at all, but I'm not sure that it had any impact on the temperature of the drinks. I have now used this product on two occasions and both times the ice we put in, despite floating down a cold river, seemed to melt pretty quickly, i.e., it was all water in less than 2 hours. It is, however, a fun concept and everyone found it to be a novel idea.

Have had a few problems with it not fitting certain bottles but I knew it wouldn't fit everything when I bought them. I wish they made something like this that would fit a standard bottle of water. These said they would fit bottles and it does not fit my daughters standard baby bottles.

It is fun and a good way to spice things up.

Neat but it doesn't work with as many foods as you'd think. Still fun to experiment.

It took a few minutes to figure out the quirks since there isn't much for instructions and the labels are not in English. Make sure you pay attention to  the arrows and that they are lined up correctly if you can't get it to work.

Overall if you are looking for a quick way to make your own infused waters and juices, it is a fun product to use. It pulses automatically when on. It does not work well with hard fruits or vegetables - but if you want a quick cucumber mint or strawberry kiwi water, this can fit the bill. It could make for a nice gift.

I received this product at a discount in return for my honest review.

I was was unable to use this with the bite straw so I bough another top for it. I'm glad I did cause I am enjoying this bottle.

The tubing doesn't fit so my son wasn't able to play with it when he got it on Christmas, but it has been a pretty easy fix. It looks really neat and is fun after you make the needed adjustments.

A bit smaller than I expected but so much fun to make. I watched a video tutorial while I made it since I cant read the directions.

Overall happy with the product, just wish it came in a bigger bottle.

It worked much better than me trying to hit the hole and squeeze it in using the bottle only.  The pump made it a bit easier.  On the down side, it doesn't really get to the bottom of the bottle so you have to pour the excess into the next bottle and go from there.  It worked out for me as I needed about 2.5.

It's a good quality bottle but the straw is way too small I gave it to the kids, It stays cool though but again due to the steel. The flip is really good and easy. Overall everything else is good only if the straw was bigger and the top was removable to easy clean.
