Toys & STEM Kits

How to shop for toys and STEM kits online

Match the age and the interest. Age ranges on the box are a starting point, not a rule. A child who loves building but has never coded may do better with a construction set first. Look for a progression: block-based coding (Scratch-style) for younger kids, moving to Python on the same hardware as they grow. Makeblock's mBot2 is designed for that path, with add-on sensors and an AI camera available later.

Check device and app requirements. Many STEM toys depend on a phone, tablet or computer. Abacus Brands' VR goggles need a smartphone running Android 8.0 or newer or an iPhone 6S or newer, and tablets will not fit. Confirm app availability for your devices, whether an account is required, and whether the app collects data from children. Check whether coding software runs on Chromebooks if that is what your school uses.

Batteries and charging. Coding robots and RC toys may use built-in rechargeable batteries or AA cells. Check whether batteries are included and how long a charge lasts, so play time is not cut short.

Large play sets. For fort kits and indoor climbers, check assembled dimensions, the weight limit, recommended ages and whether parts are compatible across sets so you can expand later. Indoor climbers need a soft landing area. For backyard playsets, look at anchoring requirements, safety surfacing and assembly time.

Safety basics. Small parts are a choking hazard for children under three; the US requires a warning label on toys with small parts intended for children aged three to six. Magnets and button batteries are especially dangerous if swallowed; keep adult collector toys with small magnets or metal parts away from young children. Look for compliance with ASTM F963, the US toy safety standard, on children's toys.

Return fees and opened boxes. Toys are usually returnable only if unopened. Makeblock accepts unused, unopened items within 30 days of dispatch, and you pay return shipping. Abacus Brands charges no restocking fee on unopened items but refuses used ones. Funphix refunds within 30 days minus 15% and does not publish shipping terms, so confirm costs before ordering a big playset. Nikola Toy requires you to accept delivery and pay return shipping and any duties on personal-reason returns. For gifts, ask for a gift receipt and leave packaging sealed until the birthday.

Shipping. Makeblock quotes 7 to 10 business days after handling and does not take international orders. Nikola Toy ships free worldwide in 7 to 15 business days, or 2 to 5 by DHL Express. Order holiday gifts at least three weeks out.

Budget tiers. VR science kits and small desk toys run $20 to $70. Coding robots range from about $100 to $200, plus add-ons. Fort kits and indoor climbers run $100 to $400, and backyard playsets more.
