Product Description

Product Description

This new tub features a great assortment of LEGO bricks and elements.


When your toddler has graduated from the Duplo stage and is ready to take the next step in his, or her, Lego journey, the Lego Ultimate Building Set is the ideal graduation gift. With 405 pieces stored in a durable plastic box with a see-through top, this set is the perfect place to let children continue to explore their imagination and engineering skills. The Lego Ultimate Building Set contains many small pieces and is designed for kids ages four and older.

With 405 pieces, this Legos starter kit allows your child to build a variety of different things. View larger.
Use wheel elements to build a car. View larger.
Kit includes one mini figurine. View larger.

The Ideal Lego Starter Kit

The Lego Ultimate Building Set includes everything a child needs to take the first steps to becoming an expert Lego builder. It includes one mini figurine, a building plate, and a wide mix of standard bricks in various colors as well as house and wheel elements.

Following the included instructions and using pieces in the starter kit, kids can build a house, helicopter, dog, and car. The only flaw is that the instructions may be challenging for younger children, and require adult assistance.

As is the case with virtually every Lego set, your child will be limited only by his, or her, imagination and perseverance. Although the kit is designed for younger children graduating from Lego Duplos, you can be confident that your child will never actually grow out of the Ultimate Building Set. All of the pieces can be incorporated into future Lego collections.

I bought this for my children and to relive my days of playing with Legos in the 1970s. The kids really enjoy playing with them. I like this generic collection of mult-purpose bricks better than the sets that are designed to build one unique item. For the price (normally around twenty five dollars), you get a reasonable amount of stuff. On the down side, there are a lot of the smaller bricks (1 x 2 and 1 x 1). After playing with this for a few days I found that my kids wanted plates, bricks (2 x 4 and 2 X 8), and wheels (my son loves to make cars). I went to lego dot com where I was able to buy these specific things separately. Also, if you want to find some odd parts from old sets (even going back to the 1970s) try bricklink dot com. It takes awhile to navigate the site, but you can buy whatever individual pieces you want used.

In summary, buy this set first from Amazon and then go to lego dot com or bricklink dot com to buy wheels, bricks and plates.

The lead paragraphs of this review are intended for the LEGO newbies who are trying to scope out the galaxy of LEGO products available for purchase, and trying to reconcile the offerings with their (or their children's) needs. Farther down in the dash-led paragraphs you'll see a more specific review of product (to wit, no. 6166 aka "LEGO Ultimate Building Set" with its 405 pieces) and a few, hopefully helpful, tips from me and others.

Perhaps you feel the tug so many of us have: LEGO has, not without reason, been accused in recent years of overconcentration on highly specialized, one-trick sets like the ones for Bionicles(TM) or scenes from high-concept movies, leaving behind in large part the "bricks in a bucket" concept that many of us grew up with in the Sixties and Seventies. Today, the advantages of having a fixed object to assemble in a one-shot kit might be outweighed by the expense of trying to assemble a good versatile collection of LEGO bricks through specialized bits and pieces from disparate specialized sets (and $$$ outlay); also, parents risk the disilllusionment the child faces ("OK, I made a helicopter--now what?"), if open play and creativity are stifled by lack of options.

As such this product - the LEGO Ultimate Building Set - 405 Pieces (6166) - is not a complete return to form from the idealized "bucket" past, but judged as an object of utility is better than many other kits or sets. Your money gets you a plastic box, rather small (specs are listed), roughly the cubic content of a large shoebox for workboots or wellies. This ensemble box is amazingly light because only about a quarter of it is filled with the collection of LEGO pieces contained therein. (It does, however, contain a 5" x 5" (12 x 12 cm) green Building Plate[see below].

No they are not cheap. No the box isn't full to even half capacity. But these toys are still around for a reason: they rock. More specifically, they are indestructible, offer immense replay value, encourage creative quiet and thoughtful play, promote fine motor skill development, and they are just plain fun.

Think about the countless cheap $3.99 and $4.99 soft plastic throw away toys you've bought over the years: invariably imported and with unknown lead content, cost pennies to make, including the polly pockets, fairies, mermaids, bratz, little ponies, strawberry shortcakes, littlest petz, etc. All of those toys are very restrictive in the type of play they permit, fall apart, and lose your child's interest after a few days.. until you buy another worthless set for their next "fix."

In the case of legos i would argue that if you just refrain from buying those cheap blister packed toys for a few months you will have saved more than enough to get this or another "flexible" set of legos. I don't care for the elaborate lego sets that have you follow intricate instructions to build a pirate ship, or harry potters house, or a star wars backdrop,etc. Those are just as restrictive and inflexible in their play.

So get this set or something similar as soon as you are sure your kid won't choke on a brick. It is something they will play with now and in the future. You'll beat inflation, you'll have it for future kids you might have, or those who might visit, and it will always have excellent resale value on e_bay.

This big "ultimate" lego box looks so big but once you open it and the bags they are in, it ends up being about 1/4 full which is disappointing. It is a good starter set but I think you need at least 2-3 of these boxes to make anything interesting over a few inches.

Update: My daughter likes these legos but has gone back to her trusty duplos since they offer more variety, height and ease of use. I will try and get a bulk set to add to these but legos are very expensive for what you get. Within the 405 pieces, many are only one tiny square big or half the depth as a basic lego - meaning you have to stack 2 on top of each other to get a basic lego height. They seem very hard to put together too. Overall I am very disappointed in the purchase.
