Lots of modes, but a bit stiff
To make the two pack, they just taped two units of brushes together, so you get two brush bases, 2 USB chargers (no charger adapter), and 12 brush heads which should last a good while.  There's not much to the brush in terms of frills.  There's a single power button on the font that will run you through all 6 modes and then cycle back to off.<br /><br />The brush heads feel like they're soft bristle but in use they felt a bit stiffer than what I would prefer.  This could be just a result of high rpm of the brush and not being used to it.  The RPM/cycle of the brush head is comparable to other common brands.  The brush will time out 30 second intervals for when you should be finishing up a section of your teeth and moving on to the next one by hitting a short pause before resuming.  Once the full cycle of intervals is finished the brush will just shut off.<br /><br />While competitor toothbrushes are made of plastic, the plastic on these feels a bit cheap but you're getting what you pay for when it's roughly $19 a unit and more premium options are upwards of $60.  It works well enough to not complain.<br /><br />The one thing that I am gonna knock a star off for is that this is a product with consumable parts (brush heads) that need to be replaced periodically.  The instruction manual says that you should replace the brush head every 2 months or when the bristles are deformed (whichever comes first).  If you replace the brush head every 2 months, you should have about a year supply of brush heads out of the box - BUT - it doesn't appear to be that you can buy replacement brush heads.  At the price of these brushes, that probably isn't a deal breaker, but it's something to be mindful of if you are consumption conscious and don't like throwing out perfectly good things.
