Review on 🪥 Ronsit Replacement Brush Heads - Compatible with 4/8/12/16/20 Count Electric Toothbrushes - Professional Care/Professional Care SmartSeries/TriZone/Advance Power/Pro Health/Triumph/3D Excel/Vitality Dual Clean (Pack of 4) by Sharon Watson

Ordered these brush heads to replace the brush heads on my Braun Oral-B PRO 1000 toothbrush. I need extra small heads for my small teeth and mouth - large heads don't reach my back molars which leads to plaque buildup. This size is perfect and fits my device perfectly. After reading reviews about how they feel like sandpaper on your teeth and how they are extremely sensitive to sand on my teeth (to the point that dental hygienists have to use polishing toothpaste instead of regular polishing products), I only have them with this one tried ulterior motives. The bristles absorb more water, or are more "porous," than the new Oral-B brush heads, which look more like tiny tufts of soft rubber bristles. Because of this, the brush seems to "pull" the teeth, I don't know how best to describe it. It doesn't look gritty. It cleaned my teeth just as well, and to be honest they look and feel the same as the old versions of the Oral-B replacement brush heads. I can't confirm their durability but they should be replaced every 3 months regardless of brand. Brand name replacement nibs range from $7.50 to $10 for EACH nib. This universal version costs $1.50 for each attachment. If you follow the recommendations and change the head every 3 months, the difference is $30-$40 for a year's supply compared to $6.
