All of these fall right off my PS4 sticks, usually after 30 minutes of play. When they are on the sticks they feel fine, but they're loose.

The stays seem to be of good quality (I've only used them for 4 days - 3/8-12) .... One seems to be a little looser in the grip as compared to the others as it has come loose twice on me on 2 separate occasions.  I use them primarily to keep my skin-tight thermal/heat dissipating shirts in place.  They are pretty thin however makes me wonder if the one is defective since the other three don't lose their grip on the shirts.  Thus the 4-stars. I'm not going directly to the company to complain as to see if they actually read these reviews and actually do anything about it.

Great grip and comfort. A little sloppy on manufacturing. L1 and r1 are slightly covered by strap and need constant adjusting to use buttons.
Update: these covers are amazing. They really do help with gaming. They have relieved the annoying slick controller feel. The analog covers do get slick during intense play but overall do improve the feel of the orginal sticks

Very nice sticks. Marched for a season in HS marching band.
Contrary to other reviews, these sticks felt VERY light to me (both pairs I used)
which leads me to a small gripe, they are a bit fragile.
Even through double layered stick tape, the first pair splintered in about 2-3 months (I think. [However the show I was playing was very rimshot heavy])

Pros: Light, comfortable, pitch-matched

Cons: a bit fragile

They're very nice but the part that rests on my nose has becone loose. Also, the metal side arms get caught in my hair when I take them off.

the straps don't feel like they add any tightness or stability.. They fit good but i they feel a little loose and the straps don't really help

Definitely helps with stick handling, but the ball is lighter and not as dense as I had expected.

No problems with the balls.  Paddles are decent quality and work well, but started noticing that the rubber padding lifted from the wood backing (around the edges).

They work great, but are tight on the wrists and loose on the upper arms and roll down.

The ball thingies that cover the end of the metal sticks don't stay in place, I had to hit them slightly with a mallet, one broke.
Also, those balls came with a sharp spike from where they were cut, I had to sand them off.

The pads are working fine. If they were wider at the bottom than the top I think my arm would feel more stable.

These feel great on my PS4 controller... only problem I have is keeping them on the controller. The smaller grip caps seem to pop off (especially on my left thumb stick) but the medium one does seem to stay on better. Now this could be because my original thumb stick was beginning to wear down. The large caps are to big for my liking (and I have very large hands). With all that said I have a medium cap on my left stick and a small on my right - this seems to be working for me.

The sticker was an added bonus. Because of the way it was packed though, my stick was curled and the adhesive isn't strong enough to keep it from peeling off (I had to tape it down).

After my original review Zacro contacted me and wanted to do right by my purchase and actually replaced my original product at no charge. Because of their customer service I have bumped them to 4 stars - symbolizing a company I would do business with again.

The ball and stick joint does not stay in place.

The sticks were a little bit thinner than I would have expected but they certainly get the job done.

When I first put these on, I liked the feel of them, they are very comfortable. At first it took a while to get used to using them, and my movements in call of duty were slightly more sensitive.

However, after about a day of use and testing them, I was in the middle of a game of call of duty and went to sprint (push down on the thumbstick) and the grip slid right off of the stick, causing me to lose control for a brief moment and resulting in my death in game.

I haven't put them back on to try again yet, hopefully it was just a one time thing because I'd like to be able to use them, but if they continue to pop off I will not be using these any more.

As stated, this stick is sensitive, but otherwise feels nice and smooth. Works fine for SSB and Mario Kart, aiming in either Zelda game or Goldeneye and Perfect Dark is very difficult. I'll try the original style replacement next time and swap springs as others have done.

If someone can make a stick this style without the sensitivity issues that doesn't require modification on my part it really would be perfect and I would eagerly replace my even slightly worn out sticks with them. As it is, this is a decent replacement only for sticks that are totally shot.
