First of all, I rarely do reviews, but the customer service I experienced with the 3Doodler company was incredible so I feel compelled to share my experience. I purchased the 3Doodler Create pen (sapphire color) for my 12 year old for Christmas. She loves this pen. We did run into some problems with it initially...after each color change it kept getting clogged, we managed to unlock several times, then finally it clogged and I couldn't unclog it, tried all suggested from instructions and decided to call customer service, called at about 8pm the day after Christmas, left a voice mail (expecting to hear back the next day) and received a call back in like 10 minutes, the lady was very helpful, but unfortunately it couldn't be resolved, she asked that I email the serial number and description of the problem to the email address in the packaging. I did this and received a response within about 20 minutes. They scheduled a video call with me the same day. The video showed them that the drive was misaligned and they offered to replace, once they realized that I purchased it through amazon they asked that I return it through amazon, but if I have any trouble to let them know and they will replace it. I did as they suggested, had no trouble, instead of return, I opted for replacement, and had the new pen in 2 days and returned the broken pen at my local ups store after we received the new one. She's been using her new pen for about 5 days now and has had no further clogs, she has made all sorts of the coolest little trinkets and it looks like I'm going to have to buy her she more filament :) Good Problems to have! , she has spent hours and hours using this pen and keeps coming up with new ideas of what she can make next. I highly recommend this product, despite our initial experience, I would totally buy it again, that's how much confidence I have that if the product does fail, The company will make it right. A few things I would like to share about the pen, it does get hot, and before I let my daughter use it, I made her read every step of the directions twice, and made sure he could demonstrate to me how to use it safely, how to troubleshoot if she runs into trouble, and how to unclog it in the event that it does get clogged. I also purchased the jet pack so she isn't tied to an outlet... she has been able to use it for 2 hours straight on one charge - it would last longer, except that the product instructions recommend not running for more than 2 hours without a little break, so when she breaks, we recharge the jetpack. I am also getting ready to order her a doodle pad. She was using printer paper, and noticed that the flexy plastic is hard to get off the paper without ripping it and paper sticking to her project. (Not so much with the regular ABS filament). To resolve this, we've been using the glossy side of a piece of poster board instead of the printer paper, which resolved the flexy plastic sticking, but hard for her to use printable templates this way, so we are going try the doodle pad. 2 packets of ABS Plastic came with the pen. and I bought some extra for her. Going to try the PLS plastic too and see what she likes best.
