very good  I  recommend

The  disk and weight keeps falling off .  But while they are on they work. Would like the option to order additional inserts

I use the water weights every day.  They are not as heavy as the standard water weights.  I like them though because The red wheel ends can be removed and extra weight discs applied.  The extra weight discs had to be ordered at Speedo.

I use as drag weight and bouyant weight.  
Drag weights are super and something that cannot be duplicated on land training.
They work well and are constructed well.  I have seen many bouyant weights break apart- never these.
Treat them carefully when transporting- it is easy to torque the connector pegs on land if you set something on or smash the barbell


Seems like these are discontinued- I sure hope that they are not.

I have been using these water barbells everyday since I received them.  They are the perfect resistance and give my arms a great work out.  They are interchangeable so as my workout increases I can change the resistance level.  They dry quickly and are easy to carry.  Definately worth the money.

So far great, no problems.
