The lake balls are exactly as described. Some are in near new condition and some have scrapes and cuts. Some are sparkling white and others a dull white/yellow. I would say these are a very cost effective way of playing with a great golf ball and if you're someone who is nervous to play with brand new ProV1's or is on a tighter budget, using these lake balls is a great and cost effective way to get confident playing with them.
I have not seen any performance drop with these balls as yet, they go my usual distances and when I catch it right (rare), the ball will spin just as much as shots with brand new pro-v's. A professional or low handicaper might notice more than me. I've not given ratings for distance, control and feel because I'm not experienced enough to rate them against anything else.
This was my first purchase from GolfOnline and it was a great experience. Looking forward to getting my next purchase lined up. Delivery to the Channel Islands was incredibly fast and organised.
