Question: Does this come as a pair of dumbbells?
Document: After filling one of the dumbbells for the very first time, I discovered it had a hole in it. It is a good concept for travelers and I can make it work with just 4 dumbbells, but the quality is not what I expected.
This is a great idea particularly for those who travel frequently. My one criticism is lack of instructions. It would have been helpful if they had included a chart that indicated how much water to add to get a certain weight. For instance - fill the dumbbells to capacity = 5 pounds per section.It would also have been helpful if they had included a basic exercise chart.
I've been using this for over a couple of months now. It works as advertised.I haven't had any problems with leaking, and the smell that another review mentioned doesn't bother me at all. I've come across products with far worse smell than this.I like the fact that if you drop this accidentally, you won't be hurting anyone or damaging anything. I also like that you can fill it to the exact weight you want, without having a bunch of weights you need to put on or take off.
Unfortunately one of the weights sprang a leak but I was able to use the rest and make the best of my 3 month trip away from weight training.
Turned out to not meet my needs . Every place I go to has a gym where I can use real weights.
They took forever to fill, then the seams leaked. Had to throw them out on my trip. Even if they didn't leak I would not want to have to fill-empty-fill...very many times.
They hardly took up any space in my luggage.Ron
These are really great for travel. i usually work out in my hotel room. They are a bit large and awkward for certain exercises. But for the most part, I am very pleased with them.
These are easy to fill & empty. Prior to travel I used a measuring cup to fill & weigh one dumbbell. While on the road I measured the water using a soda bottle. That way I knew how much weight I was lifting. I am very pleased with this addition to my travel supplies.The package was delivered two days sooner than predicted. I would gladly order from this vendor again.
So let me start by saying this is not a bad product. But you're better off bringing bands or doing pushups. These take forever to fill up, and forever to deflate/take the water out. They also don't get that heavy. Buy bands, these you will not use twice.
Answer: yes
