I ordered 4 of these pens. They either never worked, worked about 6 hours or a few days. The latter the company has agreed to replace (they have a 1 year guarantee (but suggested I was very hard on the pen. The filaments became clogged and when I thought it was clear it went through the top soft plastic element .What they told me sent for refund while it works best then cost - even a small project takes 1/2 pack if you change colors I'm willing to wait forever for the handle to change , and then find that you lose about 1/5 of each stick as it clears one color and starts a new color If they dropped the price to about half their price I'd say it's a fair price would be. But many projects fail - hence there is a huge amount of waste. In the multi-colored packs I have, I almost always run out of the color I need so you don't get frustrated with using an entire pack one color k up. It's just frustrating when you start a project and aren't sure if one color is enough for you to complete the project. Also, the handle is very unreliable and takes ages (e.g. sometimes 15 minutes) to heat up. You almost always have to use the hottest setting, regardless of head type, or you'll be waiting forever for the PLA setting to kick in. I really enjoy painting but after all my paints are gone I sadly have to leave unless they drop the price of refills significantly or give you double the contents of the pack so you don't constantly run out of a paint. The number of pieces of thread is terrible - it's all plastic, if you buy a set of different colors it's about $5 a pack, but if you buy individual colors individually they're $7-$12. My "Ruby duck mostly yellow" took three packs. of 7.99 strands (ie 75 strands) and I was still looking for more sticks. I'll quickly stop buying a cheaper brand that uses spiral plastic (this will void the warranty) but more than half is wasted - it's not paints I've ever used; I've spent over $200 on filament.
