Question: I have the espark razor scooters & these replacement cartridges look different to the ones that came on with espark? Are these the only replacements?
Document: I have ordered spark replacements twice for my sons Razor 360 Flash Rider. Each time I have received the same replacements which do not fit! Super frustrating. I still haven't found the correct ones.
Works as designed. Exact replacement. Pricing on Amazon was the best. Since I have 2 boys with Razor Scooters a two pack is ideal for me.
Unfortunately, the item, from a different supplier had the same problem. When I  previously bought these packages of replacement cartridges at the local stores, they did not have this dust filling the inside of the packaging. I hope this dust is not a toxic substance. Sadly, they are not available to buy in the local stores.
My son got the razor spark scooter for Christmas 2012 and in the few short times he was able to ride it in the cold weather between now and then he used up the spark pads that it came with. These replacements are great but are too expensive in my opinion. They don't last very long and having already paid over 60 for the scooter, we don't want to spend this every couple of mths to replace the pads.
When i got my rozor spark, I was thrilled to see all the sparks coming out. When I do a willy sparks come out. I would recomend this for anybody any day of the week. It should of been a class c scooter . I think the cartridges should last longerRazor Spark Scooter.Razor Spark Replacement Cartridge, Black, 2 Pack
I had looked in every department store for these replacement cartridges...and here they are! Delivered, quick, to my front door. My grandson is a very happy little boy! !
This item was ordered twice, from two different suppliers, and the clear plastic packaging was so clouded with a dust of some sort, that you could hardly see the actual cartridges inside, both times. Because of an out of town birthday deadline, it was necessary to present this item in it's unsightly condition, with an apology for the appearance. If the cartridges inside turn out to be defective, I was told they could be returned. That can only be determined after they are used.
I ordered the replacement cartridge for the razor scooter. It sparks and they seem to last a long time. Very good product.
We bought my grandson a razor sparkster for his 12th birthday. He appreciated the replacements, but his parents thought they wore out too quickly.
I ordered this product one day and received it the very next day. This was a gift for our grandson age 7 and it made him very happy to once again be able to make sparks fly from his razor scooter. The cartridge was an exact replacement for the original and easy to change.
