I haven't had a lot of good luck but I'm 78yrs old & maybe too late. You're still young so give it more time. Good luck!!

The only thing you're doing wrong is expecting them to work. Those things are junk! Throw them away and buy some cats.

I am a customer of All One. It's not my company. I do know they've been in existence for more than 30 years, though, because that's how long I've used All One. I am a very healthy 72 year old.

Some of our regular marbles work fine. Some are ever so slightly too big. They will roll part way, then get stuck. Ours that are transparent with a small flame-like design in the middle would get stuck, but most of our solid colored ones worked nicely. These are old marbles from about 1980-ish. Overall, half of our old marbles worked.

I've used some that were very old. They always worked fine. Never had a problem. Why is that important? I don't think they do expire.

I'm unsure. However, I have three sets of these and they out perform my old ones. Great purchase!

No. Mine has worked for several years without issue. Perhaps something is lodged in them or you have a bad unit.Good luck and hope this helps.

They have most likely lost their charge. This happens when they sit around for awhile. Send them back for another set.

They are lower to the ground. Probably would be difficult to get out of if you are older.

They usually work past the expiration date, but HP doesn't guarantee them. I suggest you write to the seller thru Amazon & ask for replacement.

How old is your house? If you have a newer not more than 12 - 15 years old it should work fine. Older than that the wiring may or may not support these devices transfer of data through the electrical system. Hope this helps

We've had 2 of these for 10 yrs. Neither of them ever had that problem. One of them just stopped working completely and the other is working well.

Contact me first by email -- dave@birley.org, and let's find a mutually convenient time to talk. As my printer and my phone are close together, and I use my printer daily, let's see if I can duplicate the problem you are having, and then we can work it out. Although I am an old retired dude now, I have had 25 years or so of tech support experience with a number of pieces of equipment. Obviously old retired dudes help folks for the fun of it, and not for money, so I am at your service!

I don't know how old you are talking about. I have one of the ones that was sent out about 3 yrs. ago. They work fine with me. Read the numbers on the site to see if it matches with your meter. I'm sorry I can't do more to help you but I don't want you to waste your money. They work great for one of 3 yrs. ago.
