Having used limbsaver products on my bows for years and having recently put a limbsaver recoil pad on a muzzleloader,I have a lot of confidence in their products.I have spent considerable amounts of money on accurizing rifles (Trigger work A must)but what about having your barrel bedded and floated or the barrel crowned.Those items are more expensive then this new limbsaver product.I don't much care what it looks like if it improves the accuracy of a rifle measurably I would put it on.I have a browning A-Bolt with a boss attachment on it.It looks terrible,but it is extremely accurate.If this limbsaver product dampens the oscillation of the barrel it stands to reason that it should improve the accuracy of the gun.Is it necessary,depends upon the gun. I'm sure we all have a lot of stuff that is not necessary but contributes to our confidence in our weapons.
