Review: A well-made, all-around fantastic butterfly trainer for any balisong flipper, seasoned or new. - This is my first ever balisong. I bought it a few weeks ago, and have been obsessed with it ever since. The beauty, the structure, and the sheer heft of it feels perfect. Imagine holding a newborn baby in your arms, but that baby is metal of metal, about six inches in length, and can cause your knuckles to hurt after several hours of flipping this gosh-dang thing because it's just so fun to mess around with. I've learned a few tricks on this, and it has really helped hone my Balisong skills. The quality is absolutely outstanding for a 12 dollar product; The metal doesn't feel cheap, although the handles do wiggle a bit after some use. It's hefty, the perfect weight for my enormous hands. It makes a satisfying *clack!* every time you do a flip, a signal that yes, you are holding a 12 dollar product and yes, this was made with quality and precision as the forefront of their motivations Mae Renneburg rating: 9/10
Review: Fun Little Trainer - Snagged this as a "Secret Santa" gift for my boss because he's really into fidget toys. He has a bunch of them sitting on his desk for people in the office to play with. This thing became the "toy" that everyone, including myself, always grabbed. It's very fun to space out and twirl this thing around while going over the days operations, or while someone else is getting chewed out. I should have bought two because I want one now.

### ⭐⭐⭐⭐ Cheap and decent
*by J***A on March 27, 2023*

Out of the 3 ordered, thus one had been by far my favorite. It has nice weight and balance, and a good feel to it. I have not dropped it, however it has gotten its worth in use and, there are some noticeable points that stick out. First and foremost, this is a system that will need tightened to preference with continued use. Secondly, at first use, there is that nostalgic scent of clp. Which wears quite quickly. Which makes me believe that this should be oiled as regular maintenance. And last but not least, the blade facing tang pin on mine had shifted out of place and to one side. Making it feel very loose, as well as inhibiting the effectiveness of the latch when in the closed position. Which is kind of a disappointing since I know the shelf life of this is not long. That is of course unless I had recieved a defective product.
