Does anyone know if the Costco app when you search in store does it truly reflect the price change automatically when they drop it or is there a delay?

Its accurate and pulls directly from the store's system. If there is a delay, it would be short because I've never encountered a different price when paying then what the app showed.

edit: The price could possibly be different is if its on manager markdown which is usually lower than listed. price ending in .00

Price change is usually correct. The availability is not, at least ij my local Costco. It feels like employees are checking SD and other deal forums. All good deals are gone within hours since they appear on Costlow or SD

Although with the screen this looks like a very advanced model the motor on the handle was weaker than our diamondclean. Just an FYI. For those with a basic model this might be similar in performance to those but not diamond clean performance

I work for Sonicare and bought one of these out of curiosity as I had never heard anything about this specific model. From my personal testing it seems more like an old 2000 series with a facelift. Might not be bad at $30 but I wouldn't spend more personally, better values to be had on other models

Brev can you do us a favor? Tell them to cover those buttons with some type of rubber..

bought brand new set from Costco over $100 , first time used the button like fell off with simple press of button to brush!!! Not sure why they thought exposing the buttons was a great idea outside of planned obsolescence

Returned it and now brushing manually cause I'm hoping they fix this design .. Might try oral b instead, my old sonic care was great, but vibration started being too low/less power to be effective.. lasted many years and buttons intact since covered with rubber
