Clasps are very secure

The clasps are very secure. The clasps come separate in the box and each one installs by sticking two metal points into indentations in the neck of the bottle. This requires some care and a bit of finger strength, and care to make sure I installed it the right way, which I didn't do the first time - Removing the backward clasp required pliers!

Once the clasps are installed, closing and opening a bottle also requires a bit of careful force with both hands. I don't think that I could open or close one of these with one hand. But this is good because it means that the seal is very tight.

Did not have a problem with the clasp as some did, it is more difficult to put on than a leather band or the more common type of metal clasps but if you put it on correctly it is quite secure. The thin and light construction of the body and band make it very easy to wear. The band is very comfortable but it is a bit stiff where it attaches to the body which makes it feel a bit wide, not a problem for me but if you have a slim wrist you might not like it. The date is too small to be much use, it should be bigger or they should just drop it altogether.

Clasps attach perfect to small, fine chains and are easy to use for arthritic hands. I've only used them for necklaces, not bracelets,  but would highly recommend.

I love this!  I have some jewelry with very tiny clasps and could never manage to put them on by myself.  Problem solved!!

These have stronger magnets than I expected. They are nice little clasps for any type of necklace or bracelet. Well worth the price $5 +\-.

The clasp is very easy to use.  I didn't find it difficult to remove links, though it was a little tricky at first.

We purchased these clasps for our elderly mothers and they both love them.  Very easy to use and now they can wear their favorite necklaces and bracelets whenever they want.  Great product!

I purchased the clasps for my Pandora bracelets. My bracelet opened and I nearly lost it.  The claps will keep the bracelet on my arm if this happens again.  The clasps are very attractive and would look nice on any bracelet.

They are nice clasps, visually quite impressive. A little flimsy - I broke one of the little hook-like locks during a ham-handed installation, it seems that they're made of a kind of pot-metal or similar, but I don't think it would be a problem if you are using these on a decorative box which will be handled with a delicate touch anyway.

Be careful of the fit - you probably cannot have the top half abut directly against the bottom half or the box won't close tightly, you may need between about 1mm (1/16") of space for it to be snug.

Note that these do not come with the hardware (screws) and it may be tricky to find something that fits. There are other versions of the clasp on Amazon that do come with the screws, and even with a small price difference, it's probably worth it.

These clasps are just what I need to help get my jewelry on securely.  Item was packaged well and was as described.
Thanks for a smooth transaction.

Holds a lot of and keeps necklaces from being knotted.  You can also use it for other items (watches, braclets, etc.)

I got these for my mother.  But I have to admit I stole one back.  We have tried magnet clasps in the past from catalogs and as seen on TV adds and they didn't work well. They were bulky and ugly so would swing around and be visible next to the charm on the necklace.  Some were hard to manipulate for her and others the magnet was too weak.

These were wonderful.  The magnet is strong enough that it doesn't break apart. It needs a little tug at the bases to separate.  The clasps are pretty and for whatever reason it hasn't slipped much so far but even if it did the pretty rhinestones aren't as tacky as some the other magnetic clasps.

I do have to admit the clasp was a little larger than I was expecting but it hasn't been a problem so far.  This was a good buy for us. I am getting a set in "gold' for my mother and a set in silver and gold for me.

I've been using this for several months and am very pleased.  Durable, strong magnetic clasp and slender.  The color is just as shown.

I have had the band for about 3 months.  I was afraid it would scratch or break, but it's holding up and I'm pretty hard on it.  It has scratched a bit but the tortoise shell look hides the scratches well.  I have to look very close to find them.  I LOVE this type of clasp.  It is by far the easiest to take on and off.  The clasp continues to work perfectly.  No sign of wearing out or slipping.  I may be very lucky that it is a perfect fit for my wrist.  That might not be true for everyone.  -The outside of the finish on the clasp has worn badly.  I don't care because it's on the bottom and you don't generally see it.  And I've been very hard on it.  I would be very surprised if it didn't look beat up.  I get compliments on how nice it looks.  I have the rose gold Versa.  I had no trouble attaching the band.

Happy to find this item on Amazon and very please to see secure clasp when it arrived. It's more secure than rings I've had in the past.

I'm very happy with this clasp so far. The market seems pretty strong still a bit paranoid that it's going to fall off and I'm going to lose my Fitbit. I just this one when I go shopping so I can get steps while pushing the cart.
