Review on SCI-CORE Training Golf Balls - Real-Feel Practice Golf Balls for Kids & Adults - Indoor & Outdoor Use - Standard Size (6 Pack) by Mark Hart

I was very pleasantly surprised at how real these balls felt and behaved indoors. I always get the best feedback on my swing. They are very strong and hold up really well despite hundreds of hits with my irons and wedges! That being said, I'll be very careful using them indoors, even in the garage. When I was training indoors, I landed a full hit with an iron on one of them and drove my shot into a 1/2 inch thick pane of glass instead of hitting the boulder wall I use for training. I broke off the corner of the glass. Glass. I don't really blame the product as I don't think it's possible to make such a great ball with limited flight but also make it safe for fragile items. But it surprised me that I could actually do it with foam. Now I'm taking precautions to ensure I've moved or protected any breakable items that might be in the direct line of a scatter shot. I look forward to using them in my garden after the winter weather. swing but didn't want to use real golf balls due to space limitations, these balls are perfect for that!
