Good substitute for 18mm silicon ptfe but not as thick
921490
As described.  Not as thick rubber as equivalent ptfe lined silicon seals, so not as right sealing for volatile solvent retention.  Tighten very firmly then it works.

Solid replacement for my AE2 ear cushions after they were chewed up by my dog. As others have mentioned, they aren't quite as nice as OEM. They are noticeably more plastic-y and thicker/firmer; however, for the price I'm not complaining. They are also a cinch to replace which is a plus in my book.

These gloves are thinner than the purple nitrile gloves I usually get from Kimberly et al. Therefore,  I expected them to break like other alternatives I have tried, but they have help up well.  My use is general barrier protection in reno projects, preparing dinner when handling meats or anything else that could cross-contaminate., and general cleaning.  For these tasks they have worked adequately. i just wish they were a little thicker, assuming thicker means more protection.  I am not examining patients.

I like the case as an alternative to silicone cases. This case is sufficiently 'tacky' to not readily slide out of a pocket or off a reasonably flat surface but, unlike silicone cases, is still easy to remove from a pocket.

I wanted, but was unable to find, one of the hard, transparent, 'clamshell' type cases for my Sony 545. This case, along with the screen protector that came with it make a good combination. It is true that the front buttons are in no way protected from moisture or dirt, which is the only real flaw in the design.

Like McB, I also thought (when I first got my previous one) that the connection for the belt clip was supposed to be forced through the small hole in the case. However, with a bit of thought and experimentation, it quickly became clear that the connector actually consists of two pieces that are screwed together. Simply unscrewing them (righty-tighty, lefty-loosey) reveals a small threaded projection that fits perfectly through the hole in the back of the case. Screwing them back together provides a safe, stable, and secure connection for the belt clip.

The fish keyfob that came with the products seems a bit strange and a physical non-sequitor. I guess it is just intended to 'sweeten' the pot as it has no connection to the other items. I'd just as soon have them not include it and give an option for a discounted 2nd screen protector or some sort of a wrist lanyard that fit the lanyard slot built into the 545.

Overall, I am happy with this product set.

Additional note (8/2012) I'm still using the same mp3 player and this case. The case has remained flexible and is easily removed for cleaning. It has successfully protected my player from modest impacts and continues to provide a better gripping surface than the player itself.

These are average quality JST RCY connectors. The wire gauge printed on the wires is 22AWG, not 20AWG as claimed by the description. The insulation feels to me more like PVC than silicone, but I'm not an expert. I had no issues soldering to the wires in the pigtails, it all worked fine. I purchased these to make some custom power cables for Somfy blinds.

This seems like a pretty good deal to me, the quantity of connectors, and the pre-installed pigtails makes for easy installation. If you're intending to solder these to longer cables, I would recommend picking up some heat shrink for a neat, clean installation.

I bought this to use for the Panasonic Lumix FH25.  The width is perfect.  The depth is about 3/8" too large but still workable.  It offers decent protection and is an excellent value at $2.99 w/free shipping. It seems to be very well-made for something at this price point.  I was pleasantly surprised.  Buy it.

I got the nylon version to use with my philips fidelio, the cable feels very premium and high quality. However, it does introduce some microphonics if you rub it against a shirt or something. I don't mind it as I am using this mainly at home sitting down without much movement, but if you are planning on listening on the road, you might want to take this into consideration.

Good fit.  Controls are accessible.  Good protection for my expensive camera.  Downside:  Silicone is slippery, I'm not confident about my grip.

This fits my eos-m with adapter + 18-135STM + 50.4 + 270exII perfectly!
Plus it's lighter than most, if not all, other similar alternatives.

cheap alternative, but not as good as the all metal one

The materials are good and the finish is fine. They are not too much bulk even if they continue to deliver a great protection.
The main problem with these is that the big one has a too narrow circumference for a lens with a diameter of 77mm. My bigger one is an hair narrower compared to the two middle ones. I had to modify it to fit my big zoom lens (see picture attached).
I was able to fit a Nikkor AF 50mm f/1.8D in the small one (the Nikkor AF-S 58mm f/1.4G does not fit), a NIkkor AF-S  28-300mm f/3.5-5.6G ED VR in the second one, a Nikkor AF DC 135mm f/2D in the third one and a Tamron 70-200mm VC G2 on the modified one.
Great value for the money.

Better than the original, has silicone pads now

This is a decent deal for this gauge and length of armature wire.  Strangely, though, it is much stiffer and harder to bend than the other brands of 3/16" aluminum that I've used in the past.  I still have some of my old stock left, so I put them side-by-side.  Yep, same size.  But, compared to this armature wire by Sculpture House, the older stuff I have bends considerably more easily while still holding its structure sturdily when put into position.  With its increased stiffness, this wire from Sculpture House should definitely hold its shape if you work with heavier clays.  Not sure why the difference in flexibility between the two same-sized wires.  Both are labeled as aluminum.  Perhaps one of them has other metal alloys included?  Anyway, it's not a huge problem...although I do anticipate a body building career in my future by the time I've finished with these rolls.

These bands made of TPU instead of silicone are slightly thicker (2.5m vs. 2.4mm) and stiffer than the original Fitbit band.  The retaining loop for the strap is easier to slide on and off and the TPU material has a slipperier feel than the original silicone band.  Band length (large) is the same as the original band.

Colors are pretty close to those pictured.  The plum/purple band is slightly lighter and a bit more reddish than the original band.  The blue band is darker than a royal blue.

The only issue that I had is that one of the bands had a small piece of flashing on the end next to the pin that was preventing it from fitting into the frame.  Once I removed the flashing, it fit the frame fine.

I was not really interested in the teal and blush colored bands, but this five band set was only a little more than three dollars more than the three band set.  I went with these, as it gave me two extra sets of pins so that I have some spares.

I bought this in the 5' length. Melts in E3D hot end heat break at 200C. Threw away most of it. FEP is not a reliable substitute for PTFE in this smaller dimension

Guitar bridge pins come in a few diameters and tapers so one must do a bit of research before purchasing. The Graph Tech website will tell you the dimensions -- especially the diameter and taper -- of all their pins so you can match what you need.

I measured my existing pins' diameter and length with a&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/6-Inch-LCD-Digital-Caliper-with-Extra-Battery-and-Case/dp/B0002JFMIO/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">6 Inch LCD Digital Caliper with Extra Battery and Case</a>&nbsp;(a great bargain here on Amazon for only $12, plus you can use this tool to measure nut and bridge spacing, string gauge, all sorts of things). I didn't have a protractor so I eyeballed the taper by drawing a straight line in MS Word and then drawing a second straight line (both the exact length of my bridge pin), stacked them, and then rotated the second line to 3 degrees. Holding one of my old pins up against my monitor to compare, I toggled the angled line a few degrees back and forth, plus and minus a few degrees. 3 degrees seemed like a match. Once I installed them they fit and stayed in.

I knew in advance that these would be shorter than my originals but the length, it seems to me, is the least important measurement, as long as they are within 1/4 inch or 3/8 or so. Diameter and taper seem to me far more important.

My original plastic pins were so bad they were bending, distorting, and getting stuck to the point where I needed a small vice-grip to get them out. I thought they would break off inside the bridge and would need to be drilled out. No such worries with these as the material used is strong and the quality is very good.

If they improved the sound the improvement was only slight to my ears. It makes sense that graphite is probably more resonant than bone, rosewood or ebony pins would be. All things considered, if I didn't have a good reason for replacing the the plastic I probably would have passed on this purchase but I don't regret getting these instead of bone, rosewood or ebony. The quality is very good.

Worked fine for silicon Mr. Spock ears...i did not actually needs the removal liquid but good to have it handy in case you need it..
