Great...once you get the 510 to fit!

I had some problems getting the unit mounted in my panel  and still having the 510 fit into the dock.  It would snap into my panel opening with no problem with clearance all around but when the 510 was put into it all that clearance disappeared and the GPS was too tight to even get out again. I had to keep removing material from the dock until the 510 no longer spread the dock so much.  I think it's just an inaccurately molded mount. That being said it's the only game in town and when you get the clearance problem solved the installation looks clean and professional.

They did think through the wiring routing in the back pretty well.  Provision is made for all the 510 cables you have to connect.

Contrary to what others have said, these fit perfectly on the YN-560 IV. I have three YNs and three diffusers. They all fit perfect. Not too tight, not too loose. The ONLY "complaint" I have is how unstackable they are when storing them. I can force one inside the other for storage but it's very difficult and makes me slightly nervous so I store them loose, but it "can" be done if you needed to. It's just going to take a bit of effort to make it happen.

What I wasn't expecting was the diffuser "grid" on the very top. Nice touch. It also has two tabs sticking out on the sides which help as grip to remove the diffusers more easily.

I am still learning to use this but I am happy with it. My biggest problem was getting the right one. I ended up ordering from 3 different places on amazon. I got 3 different extensions & this was the only one that fit . Stick with KiWi It was complicated I am disabled & I got sick & was unable to see about returning the others but I was very unhappy & can't afford to throw away $ but luckily I ordered from here & this one came & it fit. I have used it only once because of my health but I think it will be a lot of fun & I will really enjoy being able to use filters. I shoot wildlife & I am very excited about this extension.  This came like it said & fit my P510 the others said  they fit the P510 but fit the P500 which makes the extensions to small to fit the P510. Thank you . I love this

4 stars because it was unclear if it would fit my zastava pap m92 - which it did after some work. I had to make the slot continious by cutting through the strip between the 2 existing slots, and by extending the resulting single slot to a total 50 mm from end to end. I did this with a 1/2" drill bit and a reciprocating saw; and finishing with a hand file. Though a bit sloppy, it took me only about 20-30 minutes. Fortunately the sloppy cuts were hidden under the grip when assembled. The width of the existing slots were an exact fit, and so was the plate thickness - the original bolt was used to re-secure the grip without any problems. Not bad for the price!

Got it to fit, but I had to lube it up and wrestle it on to fit. I was afraid I was going to break it but finally got it to work. Haven't had that issue with other brand filters.

Fit some generic 140 round pods just fine, but when I tried to get the +3 in, I found I could get +2 in, but was dangerously stretching the elastic - more than I felt comfortable doing - in order to get the +3. Still, 4+2 is not bad at all. Sure, some guys out there would love (or say they even NEED the 3rd (7th pod)), but the game is about tradeoffs..

The product worked well, and I enjoyed the double velcro strap - felt very secure and didn't swing around like the cheap-o 3 pod belt-pack I had before. Would recommend for those willing to put a little more into a pod pack.

The 1/8th turn works fine. At first, its a real tight fit... so tight at it shaved off a small (insignificant) amount of plastic off of my 910 before it loosened up. After it loosens up, it works fine.

I finally got mine on. You've gotta really work it. Stretch. And in the end you have to push the screw in with the screwdriver, get it started in the hole. Then push really really hard to get the screw into the threads. It took me more than 10 tries. Giving up. Then trying to get back at it. It was not easy, I was going to return it but finally got it in with the stock screw. Push hard. See the picture I took to see how far the screw needs to be pushed in.

Stretch, pull, to get it started and push in on that screw hard and start screwing it in. It worked for me. I'll give it a try tomorrow at the range and see how it affects the shooting.

Put on my Keltec PMR-30. tight fit but once on it was great and didn't add a noticeable weight.

Worked great but took a little modification to make it fit properly.

I had trouble getting everything to fit my camera. I think next time I will just by name brand. Then I know it will fit properly

I've had two N104's in size Large and decided to try the N104 EVO in size XL.  To tell the truth, the increase in size from L to XL is pretty minor.  Still, it feels great on my long-oval head with broad square-ish forehead, and plenty of room between the chin bar and my Clutch Cargo chin (do a Google Image search if you don't know what that is.  LOL.)

As for quality, obviously I'm a fan, this being my 3rd one.  I will pass along one pointer though.  When pulling down the chin bar from the open position, don't grab it and slam it.  That can cause problems with the latching mechanism and sometimes leave it jammed in the closed position.  Instead, grab it and lower it about 2/3rd's of the way down, then give it a firm little push to latch it. I guess basically what I'm saying is -- be gentle with it!  It's not a car door.

Having the pinlock pre-drilled and ready to install is a real nice touch.  And I love the ratchet strap.  I know some prefer the D-rings, but not me.

I noted one bad review "26650 didn't fit". It is true they are a VERY tight fit. A bit nerve racking in fact, but that worked well for my application. Be patient and line the battery up perfectly before pushing it in.

Product is very well made, but it does not fit "perfectly" with the stock.  When I installed it, the screw holes line up, but the butt pad overhangs the stock by about 1/8"-1/4".  The overhang could be corrected with a a belt sander and patience, but if you do not have experience with this, I would recommend you take it to a gunsmith who could grind it down and finish it off for a perfect fit.

Got mine today for my g42. They are designed for both 42 and 43. The one I got, like other people said, was way too tight. You could never have got it out quickly in a jam I followed the advice and softened it up with an alcohol lamp.  Take your time and heat it gently. If you smell plastic, its too close to the flame. I warmed it up and jabbed a 7/16 inch dowell into the bottom part and moved back and forth. I then put it back on the gun to cool.  I had to due it twice to get it how I wanted. Better to do it twice than to make it too loose the first time.
Loose enough to remove easily but not so loose it could fall off. It now rattles a little when in place, but not much. It still snaps on fine. It would now come off by itself if the cord was attached to a pants loop without yanking the crap out of it.
In my opinion, you shouldnt have to spend $17 for a small piece of kydex and still have to putz with it to get it to fit. The carbon fiber is sharp looking. Id probably buy it again.

I actually bought this for my g-priv 2 mod and it fits perfectly. I didn't like what was available specifically for my mod so I thought outside the box.

Have had this WP-510 case for years and have used it numerous times when we go to Hawaii and go snorkling :-) LOVE IT!!!  It is too big for my camera though (a Canon Power shot SD1200IS).  Camera is about 3.5" wide by 2.25 High and the 'usuable' space for the camera in the case is actually more like 5 1/2 " wide (to the velcro) and 4 1/2" high.(the dimensions they list is for the entire length of the case before you roll up the velcro to close the case)  I make do with it especially after I'm in the water because the suction of the water outside the case basically takes the extra air out......  I fold the bottom/side of the case to make it easier to hold/handle.....  Do have to make sure every once in a while that your lens is centered in the blackish lens of the case otherwise you'll end up with some black on the side of your picture.  I have to laugh at reviews that don't like this and go back to a disposable camera, are you nuts!?  Those cameras give horrible pictures and you can't zoom/pick which pictures you want to develop.....  WAY better quality with your own camera in this case!!!  I also got some awesome video of 2 huge turtles and also video of whales 'talking', it is unbelievable!!!!  At first I thought the sound wouldn't come through the case well but it does :-)  I am on Amazon to buy a 2nd one before our Cruise so that my girls can take pictures too, this time will be getting the WP-410, smaller :-)
