Right fit, tips are poor quality

The heel tip never lasts long. I've worn these heels about 5 times and I already need to fix the tips because the metal is clanking so bad.

So far one of the stylus tips came off. With all the good reviews I thought the quality would be higher. I will see if it's just a fluke, and if the others hold up well, I'll update this post. As of now I'd recommend going for a higher quality stylus, the customer relations for this company is great though.

The tips are pretty worthless.  All tips broken in one weekend.  If you buy them, get a lot of extra tips.

These are alright screwdrivers, about the quality you would expect for the price.  The do the job of screwing as expected, they fit my had pretty well.  Initially I liked that each has an image of the type and size of the tip, but I have already worn some of these away (likely the cleaning product I use to get the grease off).  The stand is nice if you mount it, otherwise it is a bit flimsy.

Thought that having a replacement with metal tip would be better than OEM.  Problem: tip is smaller in diameter and doesn't fit hose very well.

Quality of case seems ok. Stylus pen tip came off at first use.

I barley use these and the tips fall off on a regular basis. Buy some glue if you intend of purchasing!

I LOVE my Fitbit, but the plastic tip came off of the clip in about six weeks. It should last longer than that, and I think the replacement clip is pretty expensive.

I rarely write reviews.  Got these earlier this week (on time), and just used them for the first time this morning.  After a ONE brisk walk with my poles for 2.96 miles in 46 minutes, the tips were badly worn (see picture).  At this rate, my first pair of tips may last two weeks of walking every day.  They wear MUCH worse than the original tips that came with my Leki hiking poles.  I do not recommend these tips for anyone who hikes/walks regularly with their poles. Terrible product...certainly NOT "extra durable."

I only used for a couple of times so far, and it worked well. I bought cheaper set from Walmart before and the tips were striped quickly. These have worked well so far.

This is  the second time I've ordered these and was satisfied with the previous order. The styluses lasted a long time.  However, I am very unhappy with the quality of the second order because the rubber tips keep falling off.  I have gone through 4 of them already in a matter of a couple of weeks.

The tip of the stylus fell off twom of the three the first day. These came from China and I waited a long time for them.

So I came to these tips having previously used the Comply TSX-500 Comfort Plus tips (size Medium) with my JayBird BlueBuds X headphones.  I originally tried the medium size of the Sport Plus tips but found that they were far too loose in my ear, so I ordered the larges.  They fit fine, but the seal is no where near as good as it was with the Comfort Plus tips.  For example, where I used to be able to have the volume on medium while mowing the lawn with the Comfort Plus tips, with these I have to crank the volume, even with the large ones.  I'm pretty disappointed with them and will probably just buy some of the Comfort Plus tips again at some point (my only gripe with them was that they would get "sweat lock" during long runs ... where one of the earbuds was plugged up with sweat and no sound came through).

As others have said it is a bit of a pain to get the tips on but once they are on its no longer an issue.

works well for beginner, tips break easily. Would do a fuller review but I gave them away. Get what you expect.

Great earphones, but the comfort tips fall off way too easily. I've paid far too much money to replace them for it to be worth it.

These work well and it's great having a stylus in every room that I might use my tablet. But there is a reason they include all those extra tips. The rubber tips become soft after a few weeks and eventually split. I use these a lot and find that I need to change the tips every few weeks.
