difficult to build. fun to use.

So this is my first experience with anything like this. It arrives in a flat piece of cardboard in a plastic bag. No instructions. A few things are printed on the cardboard telling you you can rip there, but it was really kind of nerve wracking to not have printed instructions. This too awhile to figure out how to put together because it says to make the numbers match and put the tabs there. It was more complicated than that though. Once we had it together the part that divides the screen does not fit properly at all and makes it difficult to use. That is practically the most important piece so we  had to rig it up to be still in the proper place. It didn't even have information on where to download the app to use it with.  Once we fumbled our way through it all and got it together we had fun with it. So i am giving it 3.5 stars. It needs a lot of improvement.

I received this product free in exchange for an honest and unbiased review. This opinion is my own.

Cool but super hard to use. A novelty that I might not have bought if I knew how mostly useless it is. Still fun at times and there is no problem with the tech or construction quality.

Lots of fun to build. Wings were a challenge. My son lost interest in the final dragon, which was a surprise because he usually plays with his finished sets. He hasn't touched it once since he completed the set.

This is a fun kit to build. It might take a little time to complete though. This kit is not recommended for children or beginners, since it contains a lot of parts. The instructions are complete for all three vehicles. I recommend this for intermediate/expert builders.

We recently finished building this. It did take 6-8 hours and we had a few mistakes we had to correct but it was fun and our son (age 11) is very proud of what he accomplished. Just take your time and you will have success on this project.

It was an interesting build. I was worried that I might be missing pieces while making it but it was the opposite. There are a few extra pieces. My only complaint is that once the block is on, it's hard to take it out. The instructions are fairly clear. Tho I guess it should be noted that the blocks are fairly small, maybe 1/4th the size of a normal lego block?

Great set, good challenge!  It's not the easiest to sort through on certain steps and figuring out the base was harder than it should have been.  But it was fun to build and is really gorgeous!  (and huge)

really hard to put these things together and requires more tools than a pair of needlenose pliers.  i have a feeling this present will never get finished, and my guy loves puzzles, tanks, metalsmithing... the works.  perhaps if they had a challenge level scale and an approximate build time on them it would be easier to decide which ones to purchase to at least start with so you know whether or not you're going to like building these models/kits.

Hours of building fun.  Younger builders will need adult help, but load of fun and mental challenge.

Fun to play with but somewhat difficult to use. Strong is not very long. Have to hold down button to real the line in. Also, the toy at the end of the line is not heavy enough to actually cast.

it is good but very very hard and very complicated to build.
it has 8 different cool sets.
it has cool ideas.

Instructions are tough and a child will need adult help to build. It was quite difficult for me to build, bit not overwhelmingly difficult. The pictures they show  for the next pieces to add on are quite a few pieces making it difficult to follow. I can see they did this to save on printing costs. They did however have different colored pieces then the ones provided to assist in showing the next pieces that are to be added on.
They also provide a few extra pieces in case of breakage which is nice. The plastic is flexible that I didn't have it happen.
Really neat to see it float in a pond. Basically a non powered classic RC sailboat which is fun and neat to see floating for a child. Seeing something you build come to fruitation is really pleasing for a child. My son loves it.

Fun to build although some of the smaller pieces are a little hard for my 10 yr old son to make. I don't mind putting the little ones together. It's kinds fun for me too. The nice thick paper makes them very durable.

Very fragile to build but the results is awesome. You need patient to build. Not recommend for kids they might get cut with the steel

I purchased this for my 10 year old son for Christmas.  I thought we would build it together.  It took me until March to complete and my son was not interested to sit there while we looked at confusing directions (no words - all pictures) and worked with small plastic parts and dozens of small screws you can only find on eyeglasses.  Although the plastic parts were fairly easy to figure out - the screws were only millimeters apart in size and shape - and if you make one mistake - you have to go back and fix it.  I like to build things but this thing had me regretting my decision, and at times I questioned my sanity.  But I built it!  Once complete my son found it "cool" to play with.  It moves very slow compared to what this generation of video game systems is used to, but it is different, thus my son is enjoying it - but not for hours at a time.  Overall  - for the price and aggravation - not recommended for any child under 10 and only if your kid really - REALLY - enjoys doing tedious builds trying to follow confusion directions in black and white pictures.  Not sure it is even worth replacing the batteries since replacing them will take some work the way this thing is set up.

more difficult to build than i expected.. Working on it bit by bit. Should look OK when done- I  would not recommend it to anyone without some  significant model building experience.. I've done over 20 and this is likely the most difficult

This is the third GoldieBlox kit we have purchased for our 7-year-old granddaughter. Most of the parts are basically the same as the other two. This kit, if purchased alone, would be difficult for anyone to build. There is no base so if you build according to the instructions, it is very wobbly, quite unstable.
However, if this is purchased in addition to at least one other kit, the combinations increase exponentially. My granddaughter really loves trying different configurations but gets frustrated (so do I) when things won't stay together.
