## Customer Reviews

### ⭐⭐⭐⭐⭐ Beautifully machined top performs very well
            
*by D***P on February 15, 2017*

An extremely nice top, my first of this price point and a price I was reluctant to pay.  However after finding myself more enamored than expected by my first top, a $24 ShadowSpin stainless steel top, curiosity got the best of me to move up in quality/finish to this product.  Tops aren't "all about spin times" but that remains a fascinating characteristic to observe.  My very first spin of this top on a 75mm lens fell just shy of 10 minutes...9:50 if I remember correctly, which was more than triple my best observed ShadowSpin time of 3:10.  A second spin however was somehow sloppier, barely breaking 5 minutes.A very nicely machined and polished brass, this top is much more beautiful to watch than the dark, presumably anodized finish of the ShadowSpin, but each are their own unique variant in top design, the latter being a smaller mimic of the ForeverSpin tops.  I am very curious to compare the Lambda to another precision top I ordered but at half the price....the Vorso Mk I Performance Machined top, purchased directly from the UK manufacturer.  The Vorso top has the more industrial looking design of the two, while the Lambda is more aesthetically beautiful in my opinion formed from a single billet of brass and machined with smooth, elegant curves.  Pricey, yeah, but a keeper, and still at the low end of the price spectrum when one looks at other more elaborate materials and designs.As I finish this review, my Lambda top also just finished a spin that was right at 11 minutes, on a 7-inch diameter magnifying vanity mirror that I bought for use as a spinning stage...best time yet, so better times are likely still!
  

### ⭐⭐⭐⭐⭐ The ruby makes all the difference!
            
*by L***. on May 31, 2019*

Ok, now I understand why ruby is used in those fancy mechanical watches... The smoothness that it can be ground down to is what allows this top to achieve such long spin times. I was able to achieve spin times ~11 minutes within a day or so of spinning.Side note: I was spinning on a small concave lense at first, but the frosted edges were putting nicks into the brass, so I ended up switching to the mirror recommended in the listing.
  

### ⭐⭐⭐⭐⭐ Great top, exactly as described.
            
*by H***R on February 26, 2018*

 Exactly what I was looking for...  spins nicely on any smooth surface, obviously the smoother the better.  I purchased a convex glass lens to spin this on for longer runs.On that lense, my minimum spin time is ~3mins without even trying hard.  So far my best time with just basic spinning is over 6.5mins.  All just by hand and nothing special... I imagine with a string and metal rod you could get much longer spin times.The shaft is hollow so if you can get a laser pointer or flashlight aimed well, the ruby really shines.The video attached stops at 30sec, but the top spin for another 4 minutes
