Horrible and will break if you try to tighten them up! I would avoid these like the plauge......................................

No-No-No these are the same cables as the  Mono-price I bought a few of that broke attempting to tighten them gently.

Personally, I would avoid these completely or try a single pair of cables and see what you think.

I ended up with Sonic Wav RCAs for my vintage separate component system and although each cable cost me $30+ they were worth every single penny I spent. They are not always available here so you may need to find them elsewhere but they are worth the money unless you want to build your own RCAs like most audiophiles do.

You can get really nice ends and buy some good heavy guitar coax that's pure cooper and using silver solder simply connect the ends. This requires some soldering skills but if you have ever soldered before it's like riding a bike.

It's not like your soldering resisters or caps that can be damaged by high heat from in-experience.

So either buy something better and spend the cash or build your own at the length you really need. That's the best advantage of making your own RCAs. You make them at the length you need and the quality will be there as well.

I know the next time I need new RCAs I'll be buying what I need at P.E. and building my own at a way cheaper cost per cable then you would think.

I recently lost a diamond stud, and wanted to use tighter backs on another pair to ensure I didn't lose another one. I have used twist-off types before and thought this would be a great upgrade. Yes, they went on nice and tight. Great! But I could NOT get them off today!! I pulled, twisted, tugged, retwisted.... and they were both bent beyond repair by the time I finally got them off. Seems pretty cheap and flimsy. Not a good purchase.

Only buy these if you are not planning to make the slightest effort while wearing them.... otherwise they fall out!!!
I got my avantree sacool couple of weeks ago and I was almost fascinated. These are good for running only. I read a bunch of reviews that you could used them while working out, but NO.
Everything was ok while doing moderate cardio, but then it came the tricky part. I started working out with these in order to keep my cellphone in my purse to avoid any damages while doing weights, but they kept falling off. They fall off at the slightest effort.  I tried all the different sizes of the different silicone ear buds and they kept falling off. I wore them according to the instructions and still kept falling off, which meant that I had to put down my weights arrange the earplugs and continue exercising ....this was annoying!!!! Until one day, I was doing dead-lifts of course these things kept on falling off, until the unavoidable happened.... they completely fell off and on an attempt to stopping them from completely hitting the floor, i had to drop my oly lift bar really fast which caused me to loose my balance the earplugs fell on the floor and of course I stepped on them. Now, I have completely lost all my money!!!! RIDICULOUS!!
If the product would have been as good ad they say ... it would never fall off and this accident could have been prevented. Now, I just wasted my money, I should have gotten something cheaper.

Do not stay on Feet, even when you tighten as tight as possible. If you have used spikes on wet floor or expoxy on concrete floors you know you are basically on ice skates! I am serious. These are DANGEROUS and nearly impossible to tighten correctly to be properly kept on your shoes..

Will never buy Again. I THREW these away.
My apologies for being so blunt , however if OHSA witnessed these in practise in an industrial application they would never be approved for use.

Horrible. These were not able to hold my 6lb speakers. The joints are smooth and under even a little weight slide. I tried mounting my speakers to the wall and ceiling but the mounts keep buckling and twisting, no matter how tight I made the pressure screws. Look somewhere else. These are cheap for a reason.

These are absolute junk. Tried several out of the eight pack and they would all break immediately when trying to use them I am returning them today!

I hated these! Especially the installation process. I am pretty savvy with tools and at first, I was like oh nice these are easy. Just wait until you have to get the bolts tightened.

The rubber pad did not align with the holes. I had to try using a hair dryer to heat them up and try to squeeze the bolts through. Then I had to resort to a hammer to get the bolts aligned with the squares. Well, if they would have just put the X's on the bolts to use a screwdriver that would have been SO MUCH EASIER!!!!

After I finally got all of the bolts in, it was time to put them on my roof rack. I have a 2018 Subaru Outback and the crossbars were too wide. I had to wrap them and then secure the J racks. I used black foam from a roll of cabinet liner.

At the end of the day, I finally got them on the roof rack but I was very frustrated. Which, would have been avoided if they just put the X's on top of the bolts...

They held up and we made it kayaking so I guess that is all that matters. They are not coming off my roof now which sucks but I would rather have them be an eyesore than go through the hassle of installing them again. NEVER AGAIN!

These clamps don't work at all! I mean, they clamp to the bar, but they don't stay on. My husband was doing chest flies & after a few reps the clamp wiggled up & the weight started to fall off. It could've hit him in the face! We threw them away & just went back to using the screw-on ones that came with the weight bars. As far as I'm concerned, these are dangerous & give a false sense of security.

Horrible. The clamps do not stay closed. You'd be better off purchasing thin hoops at your local beauty supply store. Don't waste your money on these.

Don't buy these. They are the cheapest sunglasses I have ever bought. I bought two pair because I thought they were such a bargain (yes, they are CHEAP), but NOT a bargain. The first pair just snapped in half when I dropped them on my wooden kitchen floor. Regrettably, I had already spent $$$ getting the Rx lenses fitted to their very CHEAP insert. I salvaged the lenses and ordered a second pair of these thinking that I may have damaged the frame from the very insignificant drop in the kitchen. Guess what? I put the Rx Lenses in the new frame and withing 2 weeks, that frame broke for NO APPARENT reason. Obviously, these are CHEAPLY manufactured frames from CHINA, known for its cheap labor and poor quality craftsmanship. AVOID THESE AT ALL COSTS.............YOU ARE WASTING YOUR MONEY. THEY WILL BREAK AND ARE NOT WORTH ONE CENT.

HORRIBLE!!!!  IF you get them blown up before they pop, they only hold air for about an hour IF YOU ARE LUCKY! WASTE OF MONEY!! DO NOT BUY!! They pop when they are barely half the size they are SUPPOSED to get to. GIVEN 1 star only because I can't give it NEGATIVE 10!!
