 "terrible product - find something else" 2010-03-02
By aSprinkling
This product is terrible. The images that it displays can only be seen clearly when the projector is about a foot from the wall. This gives a planet that is an inch or two across. In addition, it is so loud that you can hardly sit beside it to control it. Find something else. Don't waste your money.



And don't think that Discovery Customer Service is going to help you out if you do have a problem. I have been trying to get some information for a while now. The only response I can get is "take it back to the store where you bought it". They won't tell me ANYTHING else. If it were me, I would avoid Discovery products altogether.

 "My 7 year old is a total astronomy geek now!" 2009-06-06
By H. Heuser
We bought this for our seven year old this last Christmas. Every night for months afterward (until the first set of batteries died) he would recite to us at bedtime all the facts he learned about the stars, planets, earth, gravity, and the cosmos in general. I thought it would never end. I now know how much I weigh on every planet and moon!



If you have a curious child that wants to know about how the universe works this is an excellent choice. It is not only educational but fun. A very good product for children 6 - 9 years of age.

 "Images are much smaller than expected" 2009-01-13
By Treetopz (Wisconsin)
Thought this would be a fun toy for my son and while he does seem to enjoy it, the images it projects are quite small. Does provide good information on the planets though.

 "Intro to the galaxy for a 5 year old" 2009-01-09
By kellysm76 (Wilmington, DE)
I got this for my son for Christmas and he really enjoys it. It has a lot of nice features and is a good introduction into the solar system. However, 5 is probably a bit young to understand some of the facts. It talks about how many miles in diamater, which a small child just can't understand. He seems to like it though...especially since Star Wars is his latest obsession.

 "Dad" 2010-03-05
By Xilipden (San Jose, CA)
I bought this solar educational kit for my son 4th grade school science project. After reading the reviews from the others, I was skeptical about the product. Since this is the only solar educational kit on Amazon and the price is reasonable right, we decided to buy it. We received the product in two days. The instruction is straight forward and easy that my son can do it by himself without my help. We also bought the spot flash light for about $10 from Home Depot to use it as a sunlight for indoor. This worked really well for the fan, but for the light bulb you need to use the sun light as well. Overall, this product is good for young kid science school project. My son really enjoyed it.

 "Disappointed" 2010-01-25
By Matthew Nelson (Wake Forest, NC USA)
This set is exactly the same as the Radioshack Model 277-0011 "Solar Deluxe Educational Kit". As the other reviewer stated, this is poor. After returning one set for a defective solar panel, the second set seems to have the same problem. It is difficult to setup due to having to use the wrench. Compared to their Snap Circuits SC-300 (which is excellent), I don't know why the company failed to use simple snap modules.

 "This one may be tossed - tomorrow" 2009-01-02
By Amanda Richards (Georgetown, Guyana)
This one may be tossed - tomorrow

Bet your bottom dollar

That tomorrow, it'll be gone

Just thinking about, tomorrow

Clears my brain from cobwebs and much sorrow

It's no fun



When I'm stuck with a toy that's lame and boring

I just stick out my chin and grin and say, ooooh



This kit will be tossed, tomorrow

So I gotta hang on `til tomorrow

For trash day



Tomorrow, tomorrow

I love you, tomorrow

You're only a day away





Okay, maybe a slight exaggeration there, but really, this toy can't hold a candle to the Snap Circuits Jr. SC-100 Educational kit by the same company.



For starters, this one requires a screwdriver and spanner to set up, and it's extremely unlikely that a typical eight year old will be able to do the (few) projects without adult help. The instruction manual begins with line drawings and schematics for connecting circuits in series and in parallel, and continues with the calculation and formulation for such things as "how many rows of solar cells are needed to make a solar panel work for a solar musical unit of 4.5V 100mA"



After they make your head spin (without the help of a solar panel), when you get to page 10, they helpfully add "If you do not want to make any calculation, just skip and follow the simple instructions below", which is followed by a series of black and white illustrations with captions like "No.2 screw connected to No.4 screw with jumper wire"



After you get all this done, you need to ensure that the panel is in direct sunlight. You can apparently use a 100W bulb 5 inches away from the panel, but only for 3 minutes, as the heat may melt the plastic frame. (!)



We connected the panel to the motor and fan today, and put the panel on a sunny window sill. I'd like to say we were blown away, but as the kit includes no form of storage for the charge, every time a cloud passed over the sun we were out of the flying fan and into the fiery heat of the day.



You can also connect small appliances depending on the required voltage and amperage (up to 4.5V or up to 300mA), but without a battery and charge controller it won't be very effective.



While this kit has the right idea at heart, they need to work on the presentation (looks cheap), the ease of set up for the target audience (from 8 years old), the instruction manual, and above all, they need to offer a complete solar set-up that can actually make the projects work effectively.



This one is not likely to be a favorite for anyone of any age
