After two attempts, not bad.

I ordered my first cord and it arrived very quickly but was defective when I hooked it up.  I contacted the seller and they immediately responded and sent me a second cord free of charge!  The second cord works almost perfectly.  The only minor issue is that the screen sometimes flickers to black for a split-second, but it doesn't bother me too much.  For less than $5 who cares?  I only gave the product 3 stars because I needed to try 2 cords and the minor issue.

Second attempt it went perfect.
First try, the wet a couple of specks under it.  When I tried to remove them with the little sticks th
The corner I lifted to get it under bent and would no go down.  Other brands this has not been an issue.
Tip.  Be sure it is completely dust or lint free before starting.  Pulling the first one off did that.

It took as a while to figure out how to get it to work. Once we found the trick, it worked fine. We like it.

I received a discount in exchange for an hones, unbiased review. This review is a reflection of my own personal experience with this product.

Bought one.  Tried it.  Then bought another.  Nuff said.

Had trouble when I tried to order this the first time but got it straightened out and they work as expected.

The first glass I out on didn't work well when the covering didn't come off. The second attempt with the other piece worked just fine. I was able to get it on and all bubbles out. It works well with my phone case covering for added protection. Very happy so far.

The first one we ordered got clogged up somehow (we requested a return), and the second one seems to work fine.  My 11-year-old son uses this and has a ball.  It doesn't create 3-D art like some of the videos show--if you put it on the very lowest speed then it is possible to get some true 3-D stuff, but mainly you need to work horizontally and build upon that.  The results can look a bit sloppy, but that might be the individual artist.  NOTE: My son is left-handed, and had no trouble using this.  (He just uses a different finger to press the button.)  It's an interesting toy for an exceptionally creative and skilled person, but a little pricey for random folks.

I had several problems installing this. "Emptying" my tank didn't quite work, and a lot of water poured out. Then the hose from my water supply valve wasn't nearly flexible enough to attach the T-adaptor. After getting a flexible hose, I gave it another try. I put a trash bin under the toilet to catch the water, which for some reason stayed in the tank this time. But it was worth the effort because I have never felt so clean after going, and I only use six squares when I go. I kind of look forward to going now.

Mixed feelings here. This device DOES work, but the instructions, while pretty good, don't quite make the user able to understand how to make this thing work first time. It took me 3 times to get it to work right so I ended up wasting 2 cartridges. But once I did, it worked well and seems to hold the button on way better than my poor sewing was doing. So net win, but it would be nice if it were more foolproof. Needs a video.

Had to return first one. The second one has been good so far.

Not bad. The concept is good. The second one ties into this one and helps you appreciate this one more.

screwed up the first attempt and trashed the protector, 2nd attempt was perfect
larger/less perfect cutouts for the button/speaker might have made placement easier, but worked out fine

The first case I was sent didn't fit too well on the phone, and held down the volume up button. I kept trying to take the phone in and out of the case in order to fit it in without holding the button down, but taking the case on and off too many times broke the metal band near where the charging port is, because it was too thin. The reason this review is four stars instead of two is because the seller was quick to send a free replacement, and my experience with that one was better. I'd buy a separate screen protector, because the included one doesn't work very well, and I had the volume button problem on the second case as well, but I think that it's something to do with my particular phone over the case itself, since no one else seems to be having this issue. I used my brain with the second one and cut out a divot in the case so that it doesn't hold the button down anymore, and I haven't had any problems since.

First unit didn't work, replacement unit works fine. Bit fiddly to set up, but the effort is well worth it in a world where paying for wireline telephone service is even discouraged by phone companies.

First attempt failed. Spiral went in, spiral came out, cork didn't budge. There are no instructions, other than a pictorial on how to use the opener. After examining the opener, I found the screw cap holding the spiral in place was loose. After tightening it, the opener worked as advertised. So far so good. 2-for-2!

Took a bit of time to work, but eventually I got the thrugh the instructions and now I have two working remots.

It took two tries to get one that worked but this one works fine and has a good picture.  Nice night vision.
