Durable, functional, works as advertised. You can either hang it up or stand it up as the target pops out of the bottom tray and has different settings.

Works as advertised and is so durable, I have a jeep wrangler and left the top open one night when it rained and the Mpow got soaking wet and is still functioning the same as when I got it.

Just works. Ugly as hell (i.e., not for your living room display) but otherwise 100% functional.

Great product, durable, portable and serves it's purpose. We use it for service advisors in a local Honda dealer.

There's nothing really high-tech about this, yet it can be used with very high-tech equipment to do what is so frequently needed - hold it in place.  Instructions could be a bit more clear, but if you take your time with them and look carefully at the device, it will become apparent how to change bases for various situations, etc.  Would this be appropriate in a fancy limo?  Probably not.  It's not sophisticated looking at all.  But it's highly functional, NOT unattractive, and an inexpensive way to take care of a lot of functions that often we end up buying single-function items for.  This has a screw-in camera base so it can be used as a mini-tripod, and can also hold all sorts of other devices.

I use 4 stars for very good products, and simply reserve my use of 5 stars for the very best.  The 4 star rating on this is in no way an indication it's not a desirable and functional product.

It looks like this product will probably be sturdy enough to hold up for quite a while.  The only possible issue I see with it is I don't yet know how long the vacuum base will hold a cell phone (or whatever else is placed in it), and there's no way to know how long the adhesive base will last.  But I suspect the adhesive could be replaced relatively easily even if it does dry out or lose adhesion over time.  The bases can be changed quickly and easily.

A couple of things to note: make sure you have a place to store this as I can foresee the interchangeable bases getting lost when they're not on the device.  Also, I tried it recently as a tripod for my Nikon D70 and a relatively short and light telephoto lens.  It was just barely a weight this could handle.  I have since learned there is a heavier duty version that probably would work better than this - though I knew it might not work with the relatively large SLR camera.  For a light little point-and-shoot camera with a screw base, it should be outstanding.  Combine it with the self-timer or get a remote control "clicker," and you can get in your own pictures with the rest of the family.

Sturdy, functional, many different play options, remote.  It only plays CDs, however.  No problem for me, that's all I want it to do and integrates well with other Onkyo  equipment.

The price was right and the functionality was exactly what I needed.
Pros:
- Durable: This battery holder has performed admirably and has been quite durable over the past 2 months. I have this mounted externally (using hot glue) to a small autonomous robot. The little guy is still learning how to avoid obstacles, so there has been plenty of opportunity for damage to occur. I'd also add that I usually pick the robot up by the battery pack too.
- Functional: The switch throws cleanly and holds its position. My oscilloscope shows a surprisingly clean transition (at this price point and quality level) from open to closed when the switch is toggled. The batteries fit snugly, without having to force the cover on or "massage" the batteries into place like some of the other battery holders I've used.
- Other notes: The wires are connected quite securely. I certainly wouldn't recommend holding the battery pack up by the wires or hanging it from the wires in production; but sometimes things like this happen when you're tinkering and my unit hasn't suffered any visible or functional damage from my accidental misuse.
- Cheap: This battery holder is cheap!

Cons:
- Cheap: This battery holder is cheap... while the functionality is all there and I rave about the unit above, when you open the cover it is clear that the unit was assembled in a hurry using minimum effort and maximum hot snot. My holders also have a place to screw the cover on, but did not come with any screws to actually screw the cover on. For my application, this wasn't an issue, however I could see this being problematic in other applications I would consider this product for. If you have other UXCell battry holders (like the 4xAA, or 4xAAA models), you can use those screws to secure the cover on this unit.

Overall:
Love it, would buy again!

Well made, outstanding value, functions as intended.  A better design might have a few more holes for the screw in case you want to mount it slightly off center or maybe an option for a 3/8 -16 screw, but it is what it is and does what it is advertised to do.

well built, functional. Cut about a dozen SIM card so far (regular to nano, regular to mini, one mini to nano) - haven't ruined a single one. I would put 5 stars, but fee silly applying "I love it" to such a mudane piece of equipment
