3D machines are not worth the money and I'm stuck with extra wax.

The machine that goes with this sucks.  Now I'm stuck with all this "wax" and don't know what to do with it.  It's just sitting on my shelf because the 3d machine that I got with it was just NOT worth the money.

I don't even know where to begin. First off I bought this toy and we could not get it to work so we thought it must have been broken so we exchanged it for another one. We had the same problems with the second one. The wax to fill the mold would not come out of the machine. We discovered that there was a plastic plug covering the hole that needed to be removed. This was not mentioned at all anywhere in the instructions. After we got that removed the machine still did not work properly and the wax instead of going into the mold went everywhere else and left a huge mess. because the wax cools so fast it hardens before it even makes it to the mold so you just end us with a glob of wax. This toy it is defective and doesn't work.

I just installed 3D Home Architect Deluxe and I want to warn anyone else from buying this product.  It is a worthless upgrade and I have actually chosen to downgrade back to 3DHA version 3. First of all, the new functionality provided in this product is nothing to write home about.  There are more plans, and a copule of new visualization modes, but other than that, it's the same product. The big problem is that the 3D mode is INCREDIBLY SSLOOOW.  The programmers of this product obviously failed linear alegebra miserably as it can takes 15 seconds to paint the 3D screens on a Pentium III-500Mhz machine, regardless of the options.  It's much worse than version 3.  So bad in fact that it makes the 3D view totally useless for editing (one of the features I found very useful in the previous product).  The final reason to avoid this product is stability.  In the 20 minutes that I used the product it crashed on me at least 5 times.
I purchased this product based on the recomendations on amazon. However, after using it myself, I'm convinced that the recomendations were probably posted by marketing staff and not actual users.
If you're buying this product for the first time buy version 3.  If you're upgrading, save your money and don't.

I've got a 3Doodler 2.0 first, purchased locally, which was complete junk (see customer reviews for 2.0 here on Amazon). Was able to return it and purchase a 3Doodler Create. All I can say is that this is probably the most frustrating technical/creative present I've ever purchased for my kids.

I also own a 3D printer, so I have some idea about basic physics of plastic filament deposition modeling and thermal properties of various plastics. This pen doesn't take into account even basic physics of the extrusion process. Cold section of the nozzle feeding tube is too short, which puts the cold thermal break way too close to the feeding gear. Feeding is based on a worm gear, which is hardly adequate when used with hard plastics (e.g. PLA). Very little has been done to properly calibrate retraction (the part when the plastic is "sucked" back into the nozzle to prevent oozing). The results are rather underwhelming -- excessive oozing with Flex filament, large gaps in extrusion when stopping and starting again, almost guaranteed clogging when changing plastics and so on.

The last straw that prompted me to return the pen was when on a plastic change the smaller segment of the plastic noodle that was already in the nozzle got melted at the tail end when being pushed by the new plastic noodle I fed from the back of the pen. The result was an unrecoverable clog, as the melted portion ended up being thicker than the nozzle would allow to feed forward and thicker than the opening of the feeding mechanism so it won't feed backwards either. As the extruder in this pen is not customer serviceable (the "service" opening is a joke), the result was a solid plug of plastic which is impossible to remove.

You can say that my expectations were too high, but at the times when you can purchase a decent 3D printer for $300, I expected a little bit more from a $100 3D pen.

I waxed my cars 3 times a year just to keep dirt and pollen from burning in, but I couldn't always find the time and I was really hoping to cut down on the frequency if I could find something that worked better, longer. I wanted to minimize repeat wax jobs over the course of a year.

I was biased to Turtle Wax out of habit not out of loyalty, but the Turtle Ice advertising suggested the clay kit would remove any deposits right off the paint (which standard washing and waxing can't really guarantee).  I haven't tried Maguier's Clay kit but that's the next test since I can't find the Turtle Ice clay kits in stores anymore.

Back in September 2010 I tried the Turtle Ice clay kit and Ice wax on our dark-blue Mazda and it is still working for us today, which blows my mind. Rain, morning condensation, etc, all still bead off. If I were to guess I'd estimate that I might get about 10months or a year out of this before having to do it again. :)

But I will say DON'T use the liquid clay, it was a total waste for my needs and if I could have purchased the clay bar and lubricant separately at the time I would have saved some money. In my opinion, once you've washed loose dirt and grime from your car and dried it, you can start with the clay bar and spray bottle.

If you've ever used a kneaded eraser, the clay bar is a similar material and principle, but you need the spray bottle to facilitate the cleaning. And remember, you are going to be working in small increments at a time. I worked in 10in diamater circles as I worked along. So yes, this is a time-consuming and meticulous operation.

Spray enough solution on the surface that the clay bar can glide easily, like a bar of soap glides around in a tub. You aren't rubbing this like a cloth rag and at no time should the bar stick or catch or it will leave a smudge. As the bar glides along it should pick up everything, but keep checking the clay bar because each time it gets 'dirty' you'll want to fold the clay over to find a clean patch and use that. Repeat this often, as you don't want any dirt particles in the clay bar to accidentally rub the paint while you are cleaning.

While I was working I couldn't help staring at all the dirt that this thing was picking up. Invisible stuff that I'd never have guessed was there. So long as I kept spraying the lubricant over every area, the bar did its job and never smudged the surface.  But to do this I used up almost the entire spray bottle on just the one car. So keep in mind this isn't a cheap substitute for a simple washing.

Once I was done I made sure it was dry again and I used the paste Ice wax as you would normal wax and rubbed that off. It could be my imagination but the Ice wax was harder to rub off than their usual stuff, which might have been all the removed deposits from the paint or a harder coating material in the Ice wax, I don't really know. But it certainly shined beautifully.

I'm sure this does sound like more work than usual, and I'm glad I only have to do this once a year or so. Having said that, however, I felt that the quality of the results actually justified the amount of time I put into the cleaning process compared to standard washing and waxing, especially if it meant not having to do this every 4 months.

I bought this machine directly from the vendor a year ago, the version I bought was known as "v1" to the people familiar with this machine. The current machines should all be v2 by now.

First off, I can only recommend this machine if you are somewhat handy. If you never took anything apart or never fixed small toys, then I would not recommend this printer. This printer, like the DIY kits out there, will require you to know or learn how to disassemble and reassemble. This machine is the perfect example of how far 3d printing is from being a real consumer electronics device. I would say that 3d printers are still in the DIY domain.

The very first month I had this machine, it behaved strangely. The printer would stop partway into the print! This meant that my plastic was wasted. It turns out, the thermosistor (temperature sensor) in the head had a bad solder / loose wire. !!This was a good example of what to expect from this machine. While it may work some of the times, it isn't guaranteed to work 100% of the time!! I fixed the solder and it worked for a bit.

Over the course of the last year, I've HAD TO replace the nozzle, the bowden tube, the extruder arm (I managed to 3d print a replacement), and power supply ($20-$30 piece of equipment!).
Many other users have had to replace other more expensive pieces of this machine!!!
I spent my first few months troubleshooting the problems and some problems I just learned to live with.

All that being said... If you like to tinker, then this machine is a good start! I chose to replace / upgrade many parts and there are forums that you can use to figure out how to do things. Luckily, I haven't had any problems that bricked my machine.

If you like to tinker and you're still seriously considering this machine, then I think you should consider another question: is 4.5"x4.5"x4.5" big enough for you?
Some of the upgrades I did was to expand this size to a much larger size, 11"x8"x4", but I ended up spending about $200 for all the parts. If you think you will eventually want a bigger print area, then I would recommend spending more for bigger now. Monoprice has a bigger printer and Googling will give you other choices.

Conclusion:
This machine is not consumer ready but it is a good starter for tinkers whom are interested in getting their feet wet. I would recommend any extended warranty if you can get it. My power supply died week short of Monoprice's 1 year warranty.
This machine had faults and they've revised it at least a few times but some flaws are still there.

They are so busy fixing these machines that the waiting time for a service call is two weeks! You don't really get what you pay for. I don't mind paying extra for better quality and reliability, but that is not the case with Miele washing machines. I had problems with door seal for long time and finally had to trash mine (drum problem) not too long after the warranty period. We also had smell problem with this machine from second month. You need to clean the drain once a week. It wasn't cleaning as good as our previous or new machine. I am kind of glad that our Miele machine died since we are really enjoying our new Korean machine.

The machine worked good for about 2 minutes. Then it started making a strange noise and two minutes later, the foam applicator literally disintegrated splattering wax all over the car, including the plastic and the windshield. It may be the provided applicator was defective, but 2 minutes is ridiculous for a brand new product.

The first time I ordered this, I was thrilled. The quality was excellent and most of the wax was consumed so the candles lasted a long time. But the second order had very poor quality that left 10% of the wax unburned so they didn't last as long.

UPDATE: The company that manufactures these sent me an e-mail asking for my feedback, so I gave it to them stating the quality issue and how they could make me into a happy customer. Instead of replying in a normal business fashion, they attacked me. They threatened to publish lies about me. And when I complained the CEO of the company sent me an email attacking me again and stating that he personally would publish lies about me. This kind of corporate bullying should not be tolerated by Amazon.

I will never buy from them again, and I will NEVER again reply to an email asking me for feedback. Too bad there aren't negative number reviews.

I really wanted to like my multi max but... The pieces are constantly wearing out.  I'm sanding trim pieces in a regular size room and I've already gone though two of these heads.  The ends melt and the Velcro sand paper glue melts onto them.  I wish I had purchased another brand...

Disappointed that I bought something I could make myself.

I bought a 6" random orbital polisher. It's is probably a good machine, I guess I'll never get a chance to find out. I used it twice and somehow the threads in the head where the backing plate screws in stripped out. Probably my fault. Where I have a problem is that when I called Griot's to find out about getting a part to fix it, I was told that we don't carry parts. When I asked where I could find the part if not through them, they had no answer. I was told to take it to a repair shop and they might be able to. I asked how when they can't get the part to fix it. No good answer. Selling a product, no matter how good, that I can't get a part to fix makes me give this a one star rating.

Props are over all good for my custom 3d printed quad... However they are crazy expensive you only get 2 sets...

Wax is very hard and dosent melt well at all and the invisible thread is thick black like string that would need a black shirt and black back ground to work well. Don't waste your money. Sowing thread and scotch tape would work better.

I use candy molds for my wax melts.  All the ones I have previously ordered have been great but this one is awful.  After the wax had hardened, i started trying to unmold the snowflakes and every single one of them broke.  Not very impressed!

This machine is made out of plastic and you won't be able to get replacement pins due to it being an non-standard Chinese size once you BURN thru the 1000 it comes with because half will end up as trash because this machine doesn't produce a reliable product.  I returned this and am buying a machine that may cost an extra $100, but won't waste hours of my time making junk.  Please buy an American made machine and pass buy all these!!!

way too fast for polishing and variable speed doesn't work...
