I've been using these flower sticks for just over a week now and as of yet, I have had no issues with them in any way. The delivery was fast and affordable, and the products arrived securely packaged and with no signs of damage from being in transit. Customer service aside, the flower sticks themselves are extremely grippy, meaning that if you are a beginner sticker who frequently drops the sticks, you might find yourself dropping these ones less thanks to their extra grippy material. The centre stick is a good weight and length for doing both amateur and more advanced tricks. It feels nimble and easy to play and excels in performing moves such as spinning around one control stick or flipping over in midair. Plus, the tassels on the centre stick are well designed for beginners, so that if the centre stick slips down the control sticks a bit due to faulty timing or just a loss of concentration etc, the control sticks can hold it just beneath the tassels to prevent it from falling. Of course, this is not a habit anyone should develop overall if you're planning to use these sticks very frequently or in a professional environment, but I found it great for when I was just starting off and was often accidentally causing the centre stick to lose its balance.
Overall, these are excellent flower sticks for beginners but would also be equally suitable for more experienced stickers. And the fact that they glow under UV light is a nice little addition that can make for some amazing performances!
