Zard zoop Coin Motor

These are perfect for letting kids designing various styles of vibration-bots. All 20 arrived with adhesive covers still in place - which, is not always the case with the 20+ packs. I tested all 20 in this pack and they all worked without issue.The price point of 60¢ each places these in the middle of the price range for bulk packs. This is a good price for a 20 pack. If you need more than 20 of these, this is not a great deal. Larger packs (even as few as 30) can be had for 35¢ to 46¢ per motor. Doesn't seem like much, but most class project budgets aren't much either.

My class made toothbrush bots using these motors. The size is perfect and the adhesive stayed put. One issue is that the wires on the end are barely peeking through. It didn't expose enough wire to properly stay connected to the battery. When I trimmed them I noticed the second issue. You can barely get the rubber coating off without cutting the wire. It's not impossible but it takes a delicate touch. It's probably not a big deal if you are only making a couple. But prepping enough for a classroom was a big task. After they were prepped they worked perfectly. The bot vibrated exactly as we expected and the kids loved it. I would repurchase if more wire was exposed.
