Sillbird Coupons & Verified Offers | October 2026

Great STEM kit, good value!

Compared to some other brands like Thames & Kosmos, the Sillbird STEM Dinosaur Building Kit offered a lot of variety for the price. The kids spent a solid 3 hours putting together two different dinosaurs. Delivery was quick, arriving in 3 days, and I easily used the welcome discount code at checkout. It was a 15% off coupon, which really helped.

Good kit, fast ship

Bought the 12-in-1 Solar Robot Kit. It shipped quick and arrived in 4 days. Kid liked it. Pretty good overall experience. Will shop again.

Detailed review of Space Fleet

I purchased the Space Exploration Fleet for my daughter who's really into astronomy and engineering. The ordering process was smooth, and I received an email confirmation right away. Shipping took exactly 6 days to get to us in California, which was within their estimated window. Packaging was sturdy, no damage to the box or contents. Building the first model was engaging; the instructions were mostly clear, though a couple of steps required a bit of re-reading to get right. All parts were present, which is always a relief. The quality of the plastic pieces felt durable enough for regular play, not flimsy. My daughter loved the different configurations she could make. The solar panels work as described, powering the smaller components when exposed to direct sunlight. I did wish there was a small storage case for the leftover parts, but that's a minor point. Overall, it's a well-designed educational toy that provides hours of constructive fun. Customer service seems responsive based on other reviews, though I didn't need to contact them.

Great value on robot

I was looking for a good STEM gift that wouldn't break the bank and found the Remote Control STEM Building Robot here. The price was already pretty good, but I also used a first-time buyer discount which made it even better. Shipping was free because my order was over $50, so that saved me a few bucks too. My nephew loved building it and it kept him busy for hours. Felt like a solid purchase for the money.

Fun but a missing piece

I ordered the Mars Rover Building Kit for my son, and he really enjoyed putting it together. The instructions were clear, and the quality of most pieces seemed good for the price point. However, we were missing one small connector piece, which was a bit frustrating. I contacted customer service and they were helpful, promising to send a replacement, but it did delay the build. Once finished, the rover worked well and he plays with it often. Good product generally, just that little hiccup.

Cool robot for my son

Grabbed the App Controlled Robot for my kid's birthday. It was a hit! Ordering was super easy on the site, no fuss. Got it in about a week, which was fine. He's been messing with it ever since, building and rebuilding it. Says it's pretty cool how he can control it with his phone. Definitely a good buy, totally recommend it if your kid is into that sort of thing.
