So much better than a neck strap.

I am a semi-professional photographer.  I keep these wrist straps on my cameras all the time.  They are so much nicer than a neck strap.  They are very comfortable and work out great for me.  My boyfriend uses them now too.  He also loves them.

It's very comfortable on the neck. Not sure as to why you would need a quick release on it though. If you have two $2000.00 cameras, why would you worry about sharing a $16 strap? I would rather have two without the quick release on them.

This harness is designed to be a more comfortable alternative to a standard back-of-the-neck camera strap.  With a "normal" strap, carrying your gear for a long time leaves you with three options: 1) Strain your neck, 2) Put your gear in a pack and miss the opportunity for quick shots, or 3) Sling it over your shoulder where it bangs into everything.  This harness gives you a fourth option by comfortably securing your camera directly in front of you where you can reach it easily and keep it from banging around.

I shoot a Nikon D90 and this harness supports the weight well with mid-range lenses.  I'd have no qualms about mounting an 18-200mm and carrying it all day on this harness.  If you're going to carry "big glass" lenses you're probably not going to keep them on the camera while you're moving anyway, so buy a pack for the heavy stuff.  If you're really concerned about the elastic build material, there's a version of this product made out of webbing.  If you shoot with a really heavy body with a vertical grip, that may be the way to go.

Functionally, the harness is exactly what you'd expect.  You just put it your arms through the arm holes (kind of like putting on backpack with no back part).  I find it easiest to remove the camera from the harness when putting it on ... then clip the camera back into place once I've got the harness on the way I want it.  Having said that, this is not the kind of thing you're going to want to put on and take off 20 times a day.  It's easy enough to remove the camera if you want someone to take your picture, or if you need to go through a security screening.  It connects to your camera with quick-release clips that are very sturdy.

The straps are adjustable so you can get your gear to hang exactly where you want it.  This is great because if you have it too tight you can't raise the camera to your eye and if it's too loose it bangs on your belt buckle and makes it hard to walk.  The adjustabilty is perfect and the straps that connect to the camera just glide along the shoulder straps as smooth as can be.

The only quibble I have about this harness is that shooting with the camera in a vertical orientation is difficult.  It's really no problem, though.  Simply unclip one side of your camera from the harness and you're all set.  You've still got the other side secure and you can clip it right back on when you're done.

Considering that this product costs about the same as your lens cap, it's a great buy.

It's just been a few days but my neck is already much better. The portability is phenomenal as it is light and folds down to almost nothing. The adjustable height is great because my desks at home and at work are both different. Totally digging this product!

The Harness is great. There is no strain on my neck. It felt great.

Got this when I spent a whole day using a standard neck strap and got tired of it.  Haven't spent a whole day testing this one yet but just from carrying around my camera for a bit, I can tell this will be far more comfortable.  Simple to install on the camera, but I wish it came with instructions on how to actually put it on your arm/shoulder.  Took me a few minutes to figure it out but it works great once you know how.

I've read a few reviews that said the included carabiner clip could break.  I yanked, bounced, and stretched it several times and it seems secure but haven't put it through any real stress. To be on the safe side, I ordered some steel carabiners on eBay rated for 150 lbs.  Total overkill but for two I paid less than $5 so it seemed like a good insurance policy for a camera costing several hundred dollars.

I have tried three other straps for holding my ukuleles.  The standard one that dangles the uke from your neck, pulls down and makes for eventual neck pain, as well the fact that it's easy to drop in an unthinking moment. Then, there's one that was one length with hooks each end. I felt like I was wrapped in a strap. And there's one that attaches to your arm or something. When playing, I want to feel comfortable, sometimes I want to clap my hands, or just let go of my instrument, like when I turn a page or wander around.  So when I bought an inexpensive but totally awesome Eddie Finn "Minnow," I thought "why not?"  And I Love It! I can play and strum like crazy, and do solo improvisations up the neck without fear of it wiggling in my hands., and it is really comfortable.  It is removable, but I think I'll leave it on this little uke.  I would like to see a demo of it being placed on and removed from a higher end uke, but in this instance it's Perfect!

Love the B-Grip system.  Hate using neck straps.  This is the way to go.  Use this with the Travel kit, Hand Strap, and tripod quick release.

If you want to move away from a neck strap, this is a great strap.  I recently started learning more photography techniques and began going on field shoots.  I found the neck strap to really cause strain after very little time (especially if I have one of my zoom lenses attached).  I wanted to find something higher quality than the oem strap that came with my camera and after reading MANY reviews decided to give this a try.  I am so glad I did.  No more neck strain.  I did modify this a little as recommended by other buyers.  I added a couple of OP/TECH USA clip connectors and the
 Joby JB01307-PWW Camera Tether.  I connect the clip attached to this strap to one side and the tether to the other.  This gives me the flexibility of continuing to use my camera on my tripod without disconnecting everything.  Depending on the field shoot, if I am going to be shooting without my tripod, I utilize the screw for the bottom of my camera and attach the tether for added protection.  Overall a great system.  I have to say though, it does always take me a couple of tries to get it on and positioned correctly lol.

These clasps are easy  to attach to a neckless and they make it so much easier to put one on and take it off.  It's particularly helpful for older hands.

Don't waste your money on the fancy printed 2 inch straps. This one is far better. I actually bought one of these for each of my guitars; and they're far more comfortable than the 2 inch straps I was using. I own very heavy bass; at least 8 pounds. This was so much easier on my shoulder and back. Bought one for my electric and two acoustic guitars and its so much more comfortable. Yeah the design is boring and black. But that's nothing the creative mind with paint can fix! I would highly recommend these to any guitarist or bassist!

Very comfortable. I have the hand strap and now the neck strap as well. The neck strap is very comfortable and feels very secure carrying my gripped 6D, and the added ease of switching to a hand strap is great too. Great product.

I wanted to put a strap on a borrowed guitar to avoid accidents.  Since I did not want to alter the neck, I decided to try this.  It was very easy to install, and looks neater than laces.  I think it's also safer than knots, and can be removed easily if need be.  It doesn't interfere with my hand, and I can still leave the strap on when I put the guitar in its case.  Just what I needed.

After playing bass for about 26 years, I began to have some shoulder and back pain from hours of playing each week. I wasn't ready to move to one of those padded or really wide straps, so I decided to try this two inch Kepur strap. I picked my first one up two years ago. I'm not sure how it works (I think it has something to do with the space age material), but it's much more comfortable than my old two or three inch leather or cotton standard straps were. It's also the sturdiest thing I've ever seen and the end pieces will keep the strap on your guitar or bass without the use of strap locks. I recommend this highly. After two years of use, it looks good as new and my back feels much better.

This neck strap works great - the button is easy to resale whatever you've attached to it so it will be easy to use.  Thanks.......

This strap seems well-made and much more substantial than the sorry wrist strap that came with my engineered-to-be-dropped-and-repaired Canon point-and-shoot.  A neck strap seems more convenient than a wrist strap, anyway, in that you don't need to be as conscious of the camera while walking around - it's pretty much resting on your chest, instead of swinging with your arm movements or having to be held.  I feel my fragile camera is reasonably safe when using this product with it.

This strap is so much more comfortable than the strap that came with my Canon T3i.  I can now wear my camera around my neck with a telephoto lens without pain or fatigue.  I have since bought some of the adapters so that I can outfit my other camera and switch the strap back and forth.  Great buy!
