Oral-B's long-running entry rechargeable is still on sale, now badged Gum Care and shipped with two heads. It uses the older round click-on heads rather than iO, which is the main reason its running cost stays low: an 8-pack from Oral-B works out to $5 a head. One mode, a pressure sensor and a timer that pulses every 30 seconds are the whole feature list.

The two lists above are drawn from the maker’s own pages and prices, not from owner reports. Where owner discussion has been read it appears in its own section below, so the two are never mistaken for each other.
The Pro 1000 is the brush most often named when someone asks for a cheap, reliable Oral-B, and it is regularly weighed against the Sonicare 4100 and, more recently, the iO2 and iO3. Owners like its round head and its low running cost compared with Sonicare heads, and many treat it as the brush they compare everything else to.
Its weak points in owner discussion are battery life, which some find far shorter than they expected, and heads: third-party packs that claim to fit often do not, so owners end up going back to Oral-B's own. A few report cosmetic yellowing of the handle and a slow warranty process.
For a cheap first electric brush with a pressure sensor, it remains the common suggestion. Owners who want longer between charges or a visible pressure light tend to look further up the range.
The main difference owners point to is the pressure sensor, which the Pro 1000 has. Some worry it is one more part to fail; most who have been told they brush too hard think it is worth the small price difference.
Oral-B says any of its non-iO round heads fit. Owners who bought cheaper third-party heads report several that did not fit at all, so check the fitting against a genuine head before buying in bulk.
Oral-B's page gives no figure. Owners' experiences vary, and one who came from a Sonicare found they had to charge it weekly from new.
Owners weighing the two at similar prices usually choose between the Pro's cheaper heads and the iO's newer head design and quieter motor, knowing iO heads need more careful cleaning.
It is the most common budget matchup. Owners who prefer a small round head and cheaper heads lean Pro 1000; those who prefer a sonic feel and longer battery lean Sonicare.
