These dumbbells are simply magnificent. They save space, time and money.
Structurally they are solid and aesthetically beautiful. In addition I must point out that they do not make any sound when shaken. Awesome price.

Top Qualität! Sehr zufrieden mit der Mechanik und Verarbeitung. Die Einstellung in kleinen Schritten ist Top und sehr nützlich.
Ich hatte Sorge, dass der Versand wg dem Gewicht ein Problem ist. Aber die Hanteln kamen in drei größeren Paketen und waren sehr gut verpackt.
Ganz klare Empfehlung für alle die platzsparende und sehr gut verarbeitete, verstellbaren Hanteln suchen.
