    A Superior Lens for Spinning Tops
  

*by T***D on Reviewed in the United States on 9 March 2020*

I'm an avid collector of precision spin tops, and I've purchased a couple dozen glass spin lenses over the past few years to service the hobby. What initially caught my eye when I heard about this new Bruce Charles Designs spin top lens was the very affordable price of $17.95... three or four times less than I've typically spent for a spin lens.So... it's one thing to gauge the quality of a spin top, but how do you gauge the quality of a spin lens given that, in-the-hand, they often look and feel very similar. For me, that's easy... you compare the spin times you've achieved with the same top on different lenses that have about the same specs... which is exactly where the 100 mm (roughly 4 inches) Bruce Charles Designs fused silica lens really distinguishes itself. In the past few weeks, I have conducted spin testing with 12 of my favorite tops (ranging in weight from 18 to 65 grams) on my Bruce Charles lens and compared the spin times I achieved to my previous spin times on other lenses. Get this... I've set new personal best spin times for 9 of the 12 tops. Additional spin time has ranged from ~20 seconds to more than 2 minutes and has averaged just over a minute. That may not sound like a statistically relevant difference, but from years of spinning experience I can assure you, beating a personal best by a minute is a very big accomplishment. I don't know what's physically different about the BCD lens (and maybe it's just harder), but the difference seems to better preserve the inertia developed by the torque generated at launch, resulting in significantly longer spin times... and that's a metric we all seek in our spinning experience.Bottom line: I could not ask for more than a glass spinning top lens that is very affordable AND that allows me to achieve longer spin times. I bought three of these lenses sight unseen on the price alone, but the longer spin times give these lenses bona fide added value and allow me to highly recommend them to any spin top enthusiast. A truly superior lens for spinning tops!!

My name is Spinning Scotty Dodge,and I’d like tosay this has a perfectly shaped surface for spinning! The top gradually moves towards dead center! Hard scratch resistant glass that looks crystal clear! If you have a top/s you need a spinning disk! One day I’ll have a top spinning room! Good job Bruce you outdid yourself! I can spin the top anywhere I can place the disk! I love to decompress!
