I purchased a Jr. Engineer Motorized Construction Set for my nephews before the Holidays and have had nothing but problems ever since. The item took over a month to reach its destination and then it was defective due to a bad motor. The unbelievable hassle I had to go through for a "replacement" to be sent was insane. And then on top of it all I was CHARGED for the replacement and never told what additional fees and or BS was involved in the return process. This company seems like they make most of their money off of customers who didn't get what they were paying for and then just gave up after 15 minute hold times and trying to get ACTUAL customer service. Long story short: You will probably want to look elsewhere, this company is not reputable.
