I bought the cheapest one that had a pressure sensor. It was a Philips Sonicare 3100 series. It was 55$ CAD. The heads are pretty expensive but I buy bamboo ones instead
Yes, I've had a Philips one toothbrush and a sonicare 3100 (or similar, can't remember the model, but it was one of the cheapest models), and it's pretty much the same.
Entry Sonicare, but with the pressure sensor. Our first lasted over 20 years. We're 3 years into the new versions. I think they're 3100 or 4100.
I would recommend spending a few more dollars to at least upgrade to the 3100 for the pressure sensor. There is a tendency to press too hard with these electric brushes and you can really wear away your gums. The senor gives you an audible and tactile warning so you don't do that
Go for Sonicare 3100. It is the second best option. For experienced users it is the first option I'd recommend. These are best by test.
I purchased the Phillips SoniCare ProtectiveClean 3100 brush and the Waterpik Cordless Pearl water flosser. Both are still going strong three years later and are in under your budget. The brush is awesome because it has the pressure control (if you press too hard it will tell you) and it lets you know every 30 seconds that it's time to move to the next quadrant of teeth. The cordless water flosser is portable. Tip: learn to use it in your shower! Otherwise your bathroom might get a shower of its own! Maintenance of both devices is easy, just follow instructions. Make sure you change out the brush heads every 3-6 months, I highly recommend the sensitive brush heads.
