Product is great, but the delivery driver left the package on the bottom step and it was raining only about three more steps and it would have been on the porch not out in the rain.



by:

I am very satisfied , this is a great p roduct



by:

Very easy to set up and take down,



by:

Great idea and product. Haven’t had a chance to use them yet though!



by:

I love them their compact and look much better and easier then using 2"x6" blocks which I don't have to carry around any more they look more sanitary than using blocks.



by:

They are well made.



by:

This is a great product! So much better than hauling around cement blocks. They’re easy to put together and fold up to store underneath the trailer.



by:

Very Heavy duty. Assembly is easy. They stow away in their bag perfect to save space. Very pricey, but if you can swing it, worth it.



by:

Thanks Etrailer for fast shipping and delivery, little bit of a puzzle to setup at first but got the hang of it pretty quick. Heading out this weekend so will try them out, looks to be high quality product.



by:

Description was accurate. They seem well built and of good quality in materials and workmanship. I am excited to use these for a fall trip coming up should experience different conditions and know how well they will work. These are going to be used to stabilize a camper on and off the truck for stability while camped and if when we remove camper from truck.



by:

We have a heavy toy hauler
These weigh
safe blocks are perfect to support out stabilizers
The space saving for storage is a big plus



by:

Used them for the first time this last weekend. Love how sturdy they are and the magnetic feature is fantastic! They took the place of 16 of the stackable blocks in my use case. These were much easier to use then the pile of blocks i normally do for my rear stabilizers. Time will tell how they hold up but i am thinking they will do well.



by:

Compact design that folds down small and comes with a convenient carrying bag. Extremely stable, with quick and easy setup and takedown. So much better than the stacking blocks. Highly recommended!



by:

Just what I needed! Was looking for a block for our new trailer tngue as it is higher than our last trailer. I didn't mind the yellow ones I already have but have to use so many just on the tongue. What I like about the Weigh Safe is it is collapsible so takes a lot less space to store which is very convenient. Was suspect about how solid it would be but after first use I found it to be rock solid



by:

What a difference over the stackable stabilizing blocks. Easy set up, thinner than stackable of same height, sturdy and easy to slide in an out from under the stabilizer.
