I have that exact dropper post on my Ragley Big Wig right now. I’m very pleased with it. It’s smooth and has very little side to side play. I’ve had it for 3 months or so with regular use and it still works like new. The lever that it comes with isn’t the greatest and feels like it could snap with a decent crash, but it does work. For the price, I think it’s an excellent dropper post.
