Oral-B Genius 9000 CrossAction vs Philips Sonicare DiamondClean Electric Toothbrush – Don’t believe that RRP, but which is the best Black Friday deal?

One deal that comes up every Black Friday is premium electric
toothbrushes, with both Oral-B and Philips Sonicare offering some extraordinary
discounts on the RRP.

This year you have the Oral-B Genius 9000 CrossAction Electric Toothbrush reduced from £299.99 down to just £78.99 giving you a saving £221.00  which is a 74% reduction!

The Philips Sonicare DiamondClean Electric Toothbrush has also had a massive discount but not quite as much going from £299.00 down to £99.00 for a sizable £200 saving or 67% off.

Amazing deals, right?

Well, maybe not quite. They are great deals no doubt, but
the RRP is highly misleading.

Dubious Pricing

If we look at the Philips Sonicare DiamondClean on CamelCamelCamel
we can see that it does sell for £299.00 for a chunk of the year, but from August
through to October it was closer to its current sale price of £100.

The impressive 1000+ reviews for a 2019 toothbrush? The product listing dates back to 2016 at least, a and the lower price ever was £79.98 for Black Friday 2017. Each year they refresh the product page for the new model.

The Oral-B Genius 9000 arguably looks more impressive, apart from the fact it is cheaper its product page appears to only have been live since August 2018. However, the RRP is more damming here, from what I can tell, they sold the toothbrush for just 3 days at RRP before swiftly knocking 25% off and selling it for £150. It has been as low as £79.99 before, and throughout the year it seems to jump from £99.99 to £140.

So with this toothbrush, at least you are definitely getting
the cheapest price ever, albeit by £1 and the 74% discount they claim is closer
to 22% if we assume you can buy it for £100 quite regularly.

Let’s look at the Amazon Reviews

The Oral-B Genius 9000 CrossAction has way more reviews at
2345 with an average rating of 4.4 with just 7% of users giving it a 1-star

The Philips Sonicare DiamondClean Electric Toothbrush has 1018
reviews with an average score of 3.8. This model appears to have a disproportionate
amount of 1-star reviews at 20% indicating there may be something wrong with

Looking at the reviews here there appears to be a lot of complaints about quality control issues with models failing.
