These lake balls are great value; good condition with only additional sponsor's marking to deter the prouder players. They play perfectly and are loads cheaper. A good buy for people who lose a few balls, particularly in winter conditions.
I saw this in The Telegraph Shop and thought it looked very useful but not at £12-15 ! Check the price on Amazon which is a fraction of that. I keep my various coffee shop cards in it which is really convenient.
I bought a pack of three of these 18 months ago. They seemed a well-priced item with encouraging descriptions which referred to the locks being 50% stronger than others. Yesterday , one of mine suffered exactly the same fate that at least two other reviewers have experienced ; namely the loop coming out of the lock completely with no way to put it back. Looks like a design weakness and worth avoiding.
