    Quick weight changes / Rock solid feel

    I was considering other “quick change” dumbbell products, but I made the correct choice by purchasing Ironmaster! \r\nIronmaster dumbbells are rock solid, no loose rattling plates, and quick to change weight. Even as a new user, I can change plates in 30 seconds and that’s well within my typical inter-set rest interval. \r\n\r\nThe shipping was fast, arrived well packed and the customer service is fantastic. Highly recommend.

    Generational Dumbells

    I bought these recently because I was concerned about a lot of modern adjustable dumbbells either having complex mechanisms that don't last, and plastic parts failing that are required for function like safety pins, cradles, and so on. I came across a number of competitors and though they all had their pros/cons I ended up purchasing the Iron Master Quick Lock set, and additional weight plates. I have to say...Quality and Durability my friends. Generational Dumbbells is what I call them cause I'm sure with the cast-iron and steel construction, these will be around long after I'm gone. The quick-lock system is great with the ribbed screw providing a sense of real security when locked into place. The knurled handle feels great in the hands and the square shape of the plates gives a familiar shape, as well as a solid flat surface to place them on the ground if you don't have a stand. Great product IronMaster! You've got yourself a fan.

    Quality, Durable, and just awesome!

    Upon arrival everything was packaged up nicely, nothing was damaged. I figured out how the locking works without even using the guide! The instructions are pretty thorough and straight forward, even telling you how to properly care for the dumbells and what to do if rust does start to appear.\r\n\r\nI was originally going to go with RepxPepin's dumbells but was convinced into buying these. Right off the bat the price difference is insane! Rep's 85lbs is around $300 more than these ironmasters 75lb set.\r\nThese dumbells feel like the real deal!\r\n\r\nMy only real take away is the way you adjust the weights, since its not a simple turn and click away like the rep's; dropsets feel more time consuming but I dont mind since I rarely do dropsets.\r\n\r\nSo far I've got no complaints for these dumbells and definitely recommen them if your in the market for some!!

    120lb + Heavy Handle + Pro Stand 120 + EZ Curl

    I spent a few months deciding on what dumbells to go with and almost picked out the Reps but I am soooo glad I found these. \r\n\r\nThese dumbells were no brainer for me over the competition for a few reasons....\r\n\r\n- Resemble a traditional dumbell. No additional bars in the way.\r\n- Can get unbelievably heavy. I've been weight training for 12ish years and can hit 110+ on dumbell press/rows.\r\n- Ultra durable. Wise men admire simplicity, fools admire complexity. These things are very simple and thereby are rock-freaking-solid. I'll give them to my son one day.\r\n\r\nOf course they're not the absolute fastest, but you can be plenty fast with them if you organize everything correctly. I love these things and am a huge fan of the entire IM ecosystem.

    Fantastic!

    Really loving these dumbbells so far. Yes, it takes longer to adjust than other adjustable dumbbells on the market, but it's faster than spinlock dumbbells, super compact, and as durable as a fixed dumbbell(which it also feels exactly like). I don't complain about loading weight on a barbell so why should I care with a dumbbell?\r\n\r\nI did have a slight issue with mine- the knurling was off on one of the handles. I sent an email to support and pretty quickly got a response and a new handle was headed my way! Great customer service.\r\n\r\nOverall very happy with my purchase. They are exactly what I was wanting with an adjustable dumbbell.
