If you are looking to build a dumbbell home gym set, this is a good place to start. These weights are just like what I have seen/used at many gyms. The heavier weights don’t feel (knurl, metal, handle diameter, etc…) any different to me, so I plan to continue to build my set with the individual dumbbells.My package was shipped and delivered on time. I received all my dumbbells in one shipment. Great quality and a needed addition to my home gym.After reading the mostly positive reviews I decided to give these a try and am so happy I did! They are exactly what I was hoping for. They do come in separate shipments (took 3) but they were only a couple of days apart. After the first shipment my Amazon order said "delivered" which makes it seem like it's complete, and does not say anything about a partial delivery, etc. I sent the seller a message to make sure they rest would be coming and they responded quickly. I absolutely recommend these and this seller!The weights are definitely worth the money. Also, the seller was amazing to work with. The weights come in at different times. I contacted the seller because one of the sets took a little longer and they responded within 24 hours answering my question. Definitely would purchase from this seller again.I almost didn’t order these due to bad reviews. Smell - when you open the box you may smell a little rubber but I worked out with them the next day and couldn’t smell them. Rubber coating - there were some black smudges in the individual boxes that’s it. Shipping the company notified me the following day to let me know each pair comes in an individual box and ships separately. I was concerned at first because of the reviews and messaged the seller, they messaged me back every night. I received every box within a week. And love the product, loved the price and their customer service was stellar. Don’t listen to the bad reviews! I almost did. Be patient they are worth the little bit of waiting time. This was a perfect size set for me 5 through 15 pounds! 5 pairs. You won’t be disappointed.Great set. Serves its intended purpose well enough. Docked 1 star because they arrived dirty and smelled like an ash tray. And I don't mean the box they came in, the dumbells themselves have a dirty greasy film and my hands and clothes get dirty and smell after each use. Had to wipe them down.I would buy these weight againI really like these weights, but they came VERY dirty, covered in black dust or coating. I put them on my carpet and it is now stained. I ended up cutting up the box they came in and now have them on the cardboard. There is also a strong odor coming from them.
