Replacement Brush Heads for Burst Electric Toothbrush (Charcoal Soft Bristles, 4 Count, Black)

I thought it was compatible with the BURST toothbrush but it only goes in about halfway. I almost broke my toothbrush metal piece trying to jam it in. Don’t waste your money. I can’t return it because I opened one to try it out.

These brush heads are identical to the Burst brush heads, and there are more than half less than buying from Burst. I don’t know what the durability is but even if they last 50% of the Burst it’s well worth the value

they look like the burst toothbrush heads but they aren't. tongue scraper isn't on the backside of the toothbrush head and they are shiny black, not matte black.
