a set from Rep Fitness called "QuickDraw Adjustable Dumbbells" and I love them.

Pros:

1. They are adjustable in 5lb increments starting at 5lbs each and going up from there - up to 60lbs each.
2. They are quick and easy to add or subtract weight - faster than probably any other option out there.
3. Lifetime warranty - they are built like a tank and seem very solid. I'm not worried about them breaking. I hope to keep them forever.
4. The price is competitive - starting at $280 for 30lbs/pair and expandable up to 60lbs/pair for $500. I'm starting with only 30lbs and will buy the 10lbs add ons every three months (up to 60lbs each), so long as I keep using them and don't ignore them. Buying the add-ons later ends up being about the same price as buying everything all at once.

Cons:
1. Not the cheapest, but certainly not the most expensive.
2. The rack that the dumbbells sit in is good, but the numbers on the rack are hard to see - black on black. I'm using a white paint-pen to make the numbers easier to see.
3. Once I get to 50lbs or 60lbs, they start to get pretty wide.



Overall, I'm very happy with these. I'm having fun creating a workout room with my dumbbells, a bench, and exercise bands. I have a good table stand for the dumbbells (thank you D.I.), along with a fan and a bluetooth speaker. Next on the list is to install some mirrors and some better speakers for my music. Later: a better bench in the future - my cheap bench I bought used isn't that great.
