Kids aged 9+ can enjoy twice the fun with this LEGO® Technic™ App-Controlled Transformation Vehicle 42140 set. In a first for LEGO Technic sets, this vehicle toy flips over when it drives into a wall to reveal the second vehicle. No wall? No problem! Kids can turn the model over to switch vehicles. On one side is an aerodynamic tracked racer. On the other side is a tracked exploration vehicle. With suspension, a cockpit and tracks on both vehicles, plus a truck bed on the exploration truck, there’s lots for kids to discover.

Take control with the app
Kids will love using the CONTROL+ app to operate their vehicle. Using the app, they can steer the vehicle and complete fun challenges. The app experience changes for each vehicle and cleverly switches screens when the model flips.

A great introduction to engineering
LEGO Technic buildable models feature realistic movement and mechanisms, making them a top gift idea for any LEGO builder who is interested in engineering.

    These are definitely indestructible
    Size: Medium
    Both of my dogs can destroy a ball in a matter of minutes if I let them play with them (supervised) as is. Well not with these balls. They are the ONLY ones I have found that are 100% indestructible. Please only let your dogs play with these as a toy when supervised though. They go really far when throwing them, so both dogs get a good amount of running and exercise with these. I also bought these because they have the hole in the middle of the ball which is very important in the event that a dog gets one stuck at the back of their throat. This allows them to breath unlike those without this hold. It's an unlikely event, but as dog owners, we all need to be aware of this and educate ourselves on what to do if this SHOULD happen. This isn't a scare tactic, nor a reflection of this particular brand, it can happen with any type of ball. My two dogs are about 45ish lbs and the size is perfect for them, I don't want anything smaller than this. They love them. There is no annoying squeak. Really easy to wash after use. Some balls take forever to get the slimy saliva off, but these don't.

    Rusty LOVES them.
    Size: Large
    Our dog loves these balls! I like that they squeak and the texture prevents them from getting slimy from his spit. They last more than smooth balls. You do need to make sure you get the right size for your dogs mouth.

    Squeaker Does NOT Break in a Day
    Size: Large
    My mid-size, 40lb heeler mix loves these chew balls. They are easily his favorite toys to fetch, chase and chew on. We’ve had the chew balls for several months, and, unfortunately the squeaker does not break in a day. They are still going strong. Extremely durable and great value for the money.
