Good, but it's not magic
For reference, my nails aren't flaky or splitting, but they are extremely thin, flimsy and bendy. I have been using this for a about four weeks now and I find my nails aren't as prone to bending to the point of causing pain. I also find that applied under nail polish, it really does keep the colour on much longer. It hasn't worked any miracles, I still need to treat the root issue causing my poor nail growth, but this is a good solution until they grow out healthier.
I would say it is however, not that different to other nail hardener I've tried, but much more expensive.

Disappointing
Was very streaky, even after four or five coats - very disappointing

No what I was expecting
No what I was expecting. The colour is too opaque that looks artificial and chip like any other . I was expecting a much better quality. The only good thing is that dry fast

Don’t bother
This bond building serum does NOT work. I used it twice a day for 6 days with no difference to my nails at all. An expensive buy with no results. What happens after 6 days ? No mention of when to apply again. Don’t bother save your money.

Phenomenal!
I've applied 3 times a day for 4 days so far and my nails are the strongest they've ever been and the split in my thumbnail which has been permanent for many years is now fused back together and seems so far to be just as strong as the others. Time will tell if this is going to have any permanence but for now it is absolutely amazing! I'm honestly so impressed! That split thumb nail had to be kept cut short as it would easily catch on things ripping the split further into the nail which is unsightly but also painful. If this is a permanent fix I will be blown away!

Nail envy
Waste of money did not strengthen my nails. Did not prevent splitting or breaking.

REALLY works
I'm 84 and despite good health and good diet have fragile, weak and ridged nails. Additional vitamins did nothing to help, but this Bond Building Nail Serum really works for me. Whether young or old, it's an excellent product.
