After purchasing one of these spinner for my Puffco Proxy, I realized that (even at higher temps) your concentrates (after multiple hits) stay the same color as the first hit, all while slightly cooling down your concentrates while ripping. With terp pearls (I used opal and sapphire pearls) after a few hits the concentrate gets darker, and darker, and destroys the taste. After my first sesh with my Proxy, I knew I had to buy a spinner for my Puffco Peak Pro. Keep your concentrates tasting the same hit, after hit with these spinners! Thanks guys!
