Very cheap quality, bend easily. Hard to open and close once installed. I am very disappointed.

These are not very easy to open and close. I thought I was ordering the Lucky Line Flex-O-Loc key rings which look almost identical to these but are far superior in my opinion. Recommend the flex-o-loc ones instead.

These are much larger than I realized (not the products fault, I should have read the description better), but now that I have used them for a bit, they have been pretty cheap and bend super easy.  They will work ok, and the price was nice, but if you put any real pressure on these when tweezing they will bend and warp.

These are extremely hard too add items to.  They bend very easiy if the iitem has any width to it.  I would not buy these again.

Love how sturdy and adjustable the legs are but the installation is tricky. We installed them according to the instructions and the legs didn't fold open to a 90 degree angle. Also, the "locking" mechanism is too tight and making it a bit of a struggle to open and close.

Came quickly but we're very difficult to open and broke about 75% of the time. Impossible to reuse.

Not what I expected. Keep plastic bends easily.

Difficult to open or close. Not a very good product.

I like the design and the ability to have your mail go down in the base when you are away for an extended time. The negative is that the lock was very hard to install, my husband who is very handy could not get the lock to install with out damaging the lock so now we have to try to find a new lock to fit the hole.

so hard to open! break easily due to it being hard to open but it honestly does it's job, i've had it for almost a year now

It's a very durable product, but it's also somewhat stiff, so it's difficult to open and close. It would more than likely break the plastic if I were to open it up all the way.

I like those, look great.
Just make sure you don't touch them and leave fingers and when installing make sure tou won't have to re-adjust. The metal will bend and almost impossible to lay correctly after that.

Very very flexible metal and can be bumped to open. My dog has escaped many times now and I was not a fan had to secure it further to live up to it and am building one instead while temp using this towards a more permanent solution.

These are really nice once you get them on.  I had a *really* hard time getting them to close correctly though.

Pros:
-sturdy

Cons:
-difficult to install, see below

Mine had the square brackets, so this review only pertains to those who get that type of bracket.

As others have mentioned, the mounting screws are pretty bad.  I managed to get them to work, but I'm a bit worried about being able to get them out with how soft they were and how much they stripped.

A problem I had was that I found it very difficult to install the square brackets in a way that made the bar easy to slip in.  The brackets are seemingly designed that you mount them, and then slide the bar in from the top.  There are little metal toggles that you can presumably flip over to sort of "lock" the bar in place.

In reality, this was pretty much not a think.  The quality control on the toggles is terrible, and in both cases mine were too long.  This made installation of the brackets difficult for two reasons:  1.  The toggles get in the way of the screw 2. Even when "open" the toggles don't really let the bar slide in to the bracket, so it is hard to position the brackets appropriately.

Despite measuring several times and making sure my brackets are level (using a 30+ inch level), it was still very difficult and required a lot of force to get the bar into the brackets.  They claim that the bar is removable, but the design of the toggles basically prevents this from being the case.

In conclusion:  In my experience, this bar is not practically removable once installed.  Furthermore installation was much more difficult than I thought was reasonable.  However, once installed it is very sturdy and I like the grips.  This bar represents a good value and I would recommend it.  It is important to remember that a pull-up bar has to support a lot of weight and force, so with this in mind I only penalized the product one star for the installation difficulty.
