Great weight set and easy to assemble
So far so good 👍
Purchased a set of 20,25,30, and 35 lb dumbbells for home use.
The price was the best I could find online and in store. They have great reviews so I gave them a shot. All dumbbells arrived quickly and in good condition. These are exactly what I wanted and would recommend this company to anyone. I will not hesitate to order from again.
There was a rubber smell at first that lingered for the day, but other than that I’m satisfied with the dumbbells I bought. Had no issue picking up at the warehouse and no issues with communications.
Bon rapport qualité/prix, mais il ne faut pas être pressé de recevoir la livraison. Dans mon cas ça l'a pris 4 semaines.
