Because it is made of solid rubber, it has really good grip of both the tire and the ground

After all, it is Rubber!Great grip even on sloped driveway.

Great grip, low cost far superior to the yellow plastic versions that are easily crushed

The grips that are built into the bottom are also nice and provide good grip from the chocks slipping

Hard rubber body creates strong grip which making accidental damage a low likelihood

The car would not move at all while under power, so I know these work great!

Even though I was on flat ground these worked well for helping to stabilize/keep the vehicle from rolling when the drive wheels (emergency brake) were jacked up and on jack stands during my brake repair.

Perfect for preventing tire roll when jacking up & working under the car.

The shipping was fast and the chocks work as advertised

As described, fast shipping, happy customer and best price as im a shopper!

Much better quality than I expected for the price I paid.

Strong and dependable not cheaply made buy them you'll see what I mean good quality.

Better quality than I expected, lol definitely recommend these

So maybe they stink a

Only a few more bucks than the cheapest ones and 100% better quality

Solid Rubber Heavy Duty Black Wheel Chock are not "lighgtweights"

Personally, I find these chocks to be favorable when compared to other heavy-duty rubber chocks I've "smelled".

HEAVY DUTY is right, these chocks are amazingly durable!!

Fantastic heavy duty, secure chocks; I no longer have to trust those slick, timestamped, light weight yellow chocks!

and i dont believe they would have stopped the camper from rolling, they would have just broke, but these are nice rubber and heavy duty enough for me to not worry about the camper rolling away.

They are sturdy, easy to use, durable and a great value

So maybe they stink a

Heavy duty they will stay where you put them great value for this size and weight

Heavy duty and works as we need to secure cars on our steep driveway

It was exactly what I expected, great value for a reasonable price!

We have a 20ft boat and they are the perfect size for it

Perfect compact size of solid rubber to secure any small to medium wheeled vehicle

Very happy with these, perfect size, properly heavy, and obviously built to last

They have good weight and size and will hold the car in place well.

These go into the tool box of my truck so size was an issue and these are sized just right for my needs, would buy again if I needed to replace the current ones.

These are just as described - Solid wheel chocks for a good price!

Nice chocks, probably could purchase for a lot cheaper price, saw close to the same ones at Harbor freight

Exactly the same as I bought at a local store, but these are cheaper priced and I didn’t have to drive to the store

Pretty Great quality wheel chocks at a reasonable price

Great price point on these and a whole lot cleaner in storage than the 1/4 rounds of split

It has a good solid weight to it, but not too heavy either

They have good weight and size and will hold the car in place well.

The weight is not an issue

These chocks are nice and chunky and have good weight to them so they won't shift

I was surprised in how solid and light weight these are

I bought a heavier trailer and wanted a sturdier wheel chock

I previously bought some hollow plastic wheel chocks for about half the price

Since my husband loves to drive over all of the cheap plastic wheel chocks and smashes the plastic, I bought him a pair of these for the boat.

The hard plastic chocks will have a difficult time keeping traction on smooth concrete, so rubber would be more appropriate.

I like to level the camper and then give the hard plastic chocks a good whack to seat them snuggly and eliminate forward and aft movement

They are everything I hoped for, solid rubber chocks and do not slip/slide

I've decided I like the cheap yellow plastic chocks from Camco better than these

They are a very durable hard rubber , the handle makes them much easier to carry to where you will use them.

Solid, dense rubber, they more than met my expectations.

Solid, dense rubber, they more than met my expectations.

However, the smell is sooooo bad you have to leave them outside

The smell of the rubber is very strong and need to let them air out before storing them in the garage

I keep them outside the house because the smell is way too strong

No bad smell like some other reviews stated, just the slight odor of rubber

Took the risk from all the other reviews saying the smell is terrible and they are not all that bad

Heavy duty and works as we need to secure cars on our steep driveway

Needed a set of wheel chocks to use on my insanely steep driveway when working on the family cars

These are very rugged and hold the boat and trailer on an inclined driveway very good

Heavy duty and works as we need to secure cars on our steep driveway

These are far better than the cheap hollow hard plastic ones I had before.

I've decided I like the cheap yellow plastic chocks from Camco better than these

Gave away the cheap plastic ones with a utility trailer i had because its hard to sleep at night if the trailer was on any kind of incline.

I still want to keep it out of the elements; I secure my bike to my front landing gear and then also use one block to put behind my bike tire to keep it centered directly under the front of my RV; this keeps my bike from rolling to the sides of the RV and being exposed to rain and sun; very durable for heavy fifth wheel/RVs; originally bought the cheap light plastic ones from dealership, but these rubber ones are more durable and have ridges on the bottom to keep them from sliding

Very sturdy, far better than the hollow plastic ones

Cause they will stink up the entire house.

MY GOD, ONCE YOU OPEN THE BOX, THE SMELL OVERWHELMS THE ENTIRE HOUSE
