Good for the price - bristles are firmer than stated
This set would be great for travel, very lightweight, and small and it's operation is quiet.  You are given 4 30 second cycles to move through your mouth if you break it down to 4 quadrants.  As for 10,000 bristles per head I cannot see that as the case with all the gaps, however also do not have the time to pull them apart to count them.<br /><br />It's a good no frills system and you get two brush bases, 2 USB chargers, and 12 brush heads , with an on/off button to go through 6 levels of cleaning power from delicate to whitening.  Instructions say that the brush will study and remember which mode you normally use, however mine must have a steep learning curve so I guess will see what shows up.<br /><br />It's lightweight but durable and really best suited for travel.
