Bought two - one works great, the other...

I bought two of these cap keepers after always having to put my lens caps in my pockets.  I have two lenses: a Canon 18-55mm and a Canon 70-300mm.  Obviously, the 70-300mm is a lot longer and larger than the 18-55mm.

The idea of this product is simple and great.  But for some reason the capkeeper on the bigger zoom broke.  It probably got stretched a little too much, but I am not very happy with the poor quality of it.  It probably could have been made out of a better material, or put together better.  The capkeeper on the smaller zoom has stayed on the whole time and not broken.  I have tried numerous times to retie the one on the bigger zoom, but it keeps coming off, so I just put it in my pocket like I did before.

I gave this product 3/5 stars because the other one is still in one piece and seems pretty sturdy.  Not very happy with this product, but it helps a lot.  Buy at your own risk...

Ok, so I ordered two of these, and for some strange reason the HDMI cable that came with BOTH of them just doesn't work.  I've plugged them in to several devices, and they are just useless.  However, when I substitute cheap (like $5 cheap) new ones, the things work GREAT - exactly as described, and what I was looking for.  They even read when a device is turned from off to on, and switch to the new port.  I like them so much, I have ordered a third one, and am waiting for it to arrive.  I will post an update on whether or not the cable on that one is defective, too.

The one of the 2 I ordered works fine. I only received one, although I paid for two. I am hesitant to place another order for this item for that reason.

Well,I have one of these that I bought a while back that works great.  But the latest one I ordered had an intermittent connection on both sockets so it's being returned.

I have two of these. Unfortenitly I found out my second one bottom two ports do not work. You shake it and it makes noise. The first one is great and works amazingly well.

I have purchased two of these so far. The first one works wonderfully (for my husband's phone) but the second one I purchase doesn't work at all (for my phone). So be returning mine.

I bought two of these, and one doesn't work...it shorts out.  The other one is fantastic.  I will contact the company and update my review depending on what they say/do.

I ordered two of these - the reason for only 4 stars is that one did not work... however the one that did is very neat - and I would purchase again.

I bought two, one for now and one for later. One worked well but the other didn't work at all and I was passed the eligibile return date. Make sure u check them all if u order more than one.

I'very got one that works great and another that doesn't.  It could be the different locations. Haven't had time to do a complete comparison yet. Be careful who you buy it from.

I have two of these, one at each end of the house, with the wifi router they are extending in the middle.

They work very well, but I did find an interesting problem...one of them was plugged into a power strip (the other is in a wall plug) and the one in the power strip kept causing problems.  The network would appear available with a strong signal, I could connect to it, but actual access to the internet was either blocked or intermittent, until I would unplug the Diamond unit, at which point the network worked fine (albeit w/a lower signal level).  I would plug the diamond back in and it would work again for a while and then start behaving in the same way again.  I actually returned one unit because of this, and ordered a replacement.

The replacement starting doing the same thing.  Feeling that it wasn't very likely I'd get two units w/exactly the same problem in a row, I decided to attach it to a second  power strip in the same area, and it has worked fine since then.  I have other devices plugged into the first power strip that are working fine, so it may be some subtle issue between the Diamond unit and the first power strip that was leading to the problem.  So if you have issues, try another power source.

I still love this product...great form factor and easy to set up and use, and does a very good job of extending the wifi signal.
