I got a couple from the first go around for two of my grand kids. I had to open them up for a complete inspection. For the price they're good enough for two kids. I found that treating the bearings with a bit of Tuff Glide greatly improved the spin time, still kind of noisy though.
Now I want to find one of a bit higher quality, bu t like you $175 is way to much for me to pay so I can enjoy fidgeting! Since you've entered the market somewhat do you have any recommendations as to a good quality spinner that won't break the bank?
