Entice, dumbbell for 20, unfortunately declined. I have read too imprecise first the description. The set consists of a barbell and 6 discs = a dumbbell. Would have liked 2. OK, that's stupidity. To save costs actually a good idea: you fill the weights plastic with sand instead of using metal. My warning also impervious to many others. However, due to the lower density the dumbbells must be significantly larger, ie, really large and therefore difficult to handle. Delivered 4x 2.5kg and 5kg 2x. Means that you can realize from total weights multiple of 5 kg. That's roughly arg if you want to increase. For some exercises too little, others too much. Try to make 7.5kg with 2 + 1, the asymmetry is not really practical. In addition, the discs are not flat. Once 2 disks it done at once again both lots. Man must then align each other, ie turn to the parallel, so that the whole is stable two discs. Not good. So all in all not useful for me and back again unfortunately.
