Query: Big Disappointment

My 8 yr old son is a big fan of the Magnetix Products. He saw the Magnetix MagnaWorld Series in a local Toys R Us and begged for it for Christmas. We purchased the Skyscraper Series and the City Series. It is such a huge disappointment!! It is extremely difficult to manipulate. It is only magnetized on the bottoms and tops of the walls- not on the sides- making it virtually impossible to build any of the models (unless you are an octopus). Even my very adept husband found it frustrating when trying to help. Magnetix, in general, are way too pricey but I definitely would NOT recommend the "MagnaWorld" line to anyone. It is going back to the store ASAP.
