No good reason to spend more
An electric toothbrush was a commitment when I bought my first Sonicare toothbrush.  I was using a new dentist and his patients only used Sonicare.  At the time, a single brush and charger were around $125-$150.  I'm on my second Sonicare in just over 20 years.  The brushes were roughly $40 for six on sale at Costco.  The Sonicare brushes last about 2 months.  $40 / year is not a lot to spend,  Then, with one brush left and no Costco sale in sight, I took to Amazon.  I tried three different generic brushes. I am on my second box of Jibitee brushes.  I think they are as good if not better than the original product.  They keep the same vibration and sound levels from start to finish. And on Amazon, the Jibitee brushes are less than half the cost of the originals on sale at Costco.  I'm sold.  Great product.
