These were pretty easy to use. They don't accommodate all types of jars though. At least not the ones I bought.

These worked pretty good so far.  I wish they were slightly better quality, but for the price you cannot go wrong.  I have only used them once so far.  The ear piece was slightly uncomfortable for me, but my husband did not complain at all.

These were easy and nice to use. My only two beefs with them are, that they are made for lag screws and not thur bolts; also the metal moves a bit when kids are swinging. They should have made them out of thicker steel.

They were easier to use than I thought they would be. I brushed my hands often with a dryer sheet to lessen the static electricity. Was surprised that they didn't skitter away, but just stuck to the plastic bag when they escaped. No mess to clean up.

These cameras were pretty easy to install and use. The app could use a little work and adding some kind of auto on/off in wake sleep modes would be helpful. Overall a good purchase.

Love these, they are easy to use! I just rinse them off and place them back in the storage bag they came with. I may have to purchase an additional set as the camp site we used them on was pretty level but I still used all of them to get our camper level.

Simple easy to use and work great. I'm a little worried about how the foam will hold up, but not horribly worried.

a little bit smaller than I expected but they got the job done (a single power cord was all that would fit but that's all I needed for this job)

easy to use, the adhesive seems pretty strong.

Pretty simple to use. I really like the flexible cable. I order our them.  I received one of each color.  Easy to set the combination.

Pretty easy to use after figuring out the instructions.

Easy to use  but the clips were a little difficult to put on.

These are fairly easy to use.  Making sure the ground is nice and level is one of the most critical parts of using these and pays off in the end.  At first I was disappointed that the bottom half of the mold is open and creates one continuous piece instead of individual pavers, but it saved on sand for the joints and made a stronger slab.  It creates joints that only go down half way in the center of the mold and you can't tell any difference after you sand the joints anyway so it really isn't a big deal. Near the end of the project the molds started to arch a little.  Wish the plastic would have been a little stronger, but that is about the only complaint.  We are happy with the results.

These are so easy to use the only question I have is what took me so long to buy them!!

These are great!  I did not have any issues using them when they were wet, although it does say on the instructions to only use when dry.  I have put them through the dishwasher and they help up perfectly.  Really easy to use.

Worked pretty easily for me.  I only needed 2 of them, and will unlikely need many (any?) again.

Easy to install, worked great.  I used it to splice a rear view camera to my reverse lights.  Wires are held in tight, so I'm not worried about them coming out.
