XMark Fitness Black Bumper Plates Pair

I bought 4 of these because they were free shipping and I live in Alaska. It typically costs me more to ship weights than buy them. The bumpers are of decent quality, they are used regularly. The reason I gave these 4 stars instead of 5 is because they are a no/low bounce bumper. They hit the concrete floor in my garage gym like I am dropping regular plates. I have an economy set of bumpers from Pendlay and they actually absorb the impact with a low bounce. Overall I am happy with the purchase, but buyers should be aware that they are very solid rubber and would be best used on a platform with 1/2" rubber on it.

I purchased sets of XMark 10 and 25lb bumper plates several months ago and have been very satisfied with my purchase, so much so that I just recently ordered some 45lb plates. They are very well constructed and stand up well to being dropped repeatedly. Unlike some bumper plates that are exceedingly wide, these plates take up no more room that traditional olympic weights, so I can load up the bar when doing deadlift and still have room for collar locks. The only reason I didn't rate this product with 5 stars is that one of the 25lb plates was about a half pound light.

Good quality bumpers. Very little smell out of the package and none after a few hours. I saw one review mention that these did not stand up to use well and cracked after use. In my experience these are very solid bumpers and probably would only break if you dropped a bar and just a 10 on each side over and over.Very pleased. Will continue to buy these bumpers in the future.

I've used bumper plates from several different manufacturers and I will say that these have been as good as any. No problems at all for Crossfit-type workouts and pure strength training workouts despite some heavy use.One issue: These are new plates, and are covered in a layer of protective oil. Make sure you clean them off carefully with a rag before you use or store them, especially in a dusty or dirty environment like a garage gym.

I bought these for my mother to start her training on the deadlift. These are AWESOME. They are very sturdy, and with a plate pushed tight up against it and some good collars for the barbell, they don't bend even with 35's on the side of them. Beware, you may want to store them outside for awhile. The smell is very strong at first.

I have the 10, 25, and 45lb plates. The 10 lb plates did not withstand a month worth of use with once a week power cleans and snatches. They fractures where the collar inserts into the plate. The 45 and 25lb plates are going strong...so far. Avoid the 10 lb plates for sure.

I wanted some bumper plates smaller than my 45s for floor exercises under 135 lbs. These work well, I did remove one star because they were kind of greasy when they arrived.

They don't feel like 10lbs and are slightly bigger in diameter than my 45lbs bumper plates. The 45lb bumper plates aren't Xmark and may explain the slight difference. No odor to the 10lb plates. Good product other than the 4mm dliameter size difference.
