I very dubiously ordered the recent TSV after trying every nail strengthener on the market with very limited success and I have to say I'm impressed. The peeling has definitely improved and I actually have some free edge for the first time in ages. I should point out, however, that it certainly does not last a week on my nails and peels off after a bath no matter how long before I have applied it. I've also noticed that the edges seem to melt away when I have my hands in hot water even when wearing the old marigolds. I really like the moisture oil which absorbs very quickly and isn't heavy and gloopy and overall can honestly say I would re-purchase.
