- Kits contain small parts and are not suitable for children under 3. Children under 14 should build with an adult.
- Only use the power supply or battery type listed on the product page.
- Never leave lithium batteries charging unattended, and stop using any battery that is swollen, hot or damaged.
- If your kit needs soldering, work in a ventilated area, use a stand for the iron and wear eye protection.
