Over the course of 5 months, I got 4 Cap dumbbells (two 25 lbs and two 45 lbs, if you are wondering, I found my 30, 35 and 40 lbs dumbbells at a local Canadian Tire).
Price: Yes, shipping is free, but I found that if you compare the price to what they offer at a competitive local store, it's pricier online by at least 10$. That's probably because shipping costs are directly included in the listed price, which makes sense for an article that is that heavy. Still, you should look around at local stores to see if you can find a similar product for cheaper.
Availability: Maybe it's different where you live, but in my area, it was very hard to find a standard grip compact (no rubber coating)dumbbell at 40 lbs or lighter and there was nothing in the 45+ lbs range (scary, I know) so it was a blessing to find them online, at least for the 45-60 lbs range.
Quality: The 25 lbs dumbbells were perfect. The grip was clean and they were both 25.4 lbs. The 45 lbs dumbbells were a bit more problematic, though nothing too upsetting. First, one was 46.8 lbs and the other one was 47.6 lbs. I'm not too fussy about my dumbbells weighting an exact multiplier of 5, but I do appreciate it when they weight exactly the same, though to be fair, it is only a 0.8 lbs difference (plus I can swap between sets). Equally, the grip had a few bumpy artifacts... nothing that would cause a serious injury, though definitely enough to irritate the hand in the long run. That being said, 3 minutes with a file solved the problem.
So overall, it a great's product with a few minor blemishes. Well worth the money if you can't find it in a local store in your area.
