Philips Phil 9300 Black Philips 9300 Black

This unit is amazing, while it actually functions. This is the third diamond care unit I have personally owned, and also the third unit to cease functioning (each unit only lasting a year or less). The first unit's metal shaft (where the toothbrush head attaches) became loose and started making a loud buzzing sound, which progressively got worse until the brush no longer pulsated. It had never been dropped, and I had always been very careful with how I handled it. I contacted Phillips in order to receive a replacement, as the unit was still within the 2-year warranty, and was informed that I would need to return my current brush to them before they would ship out a replacement. I purchased a cheap battery operated toothbrush to use in the meantime and received a replacement diamond care in about 1.5 weeks. The replacement arrived and functioned for about a year. Once again, the exact same problem happened. Mind you, this time I was even more careful with with the brush. At this point, I was incredibly annoyed by the quality of this product. I'm not one of those people that expect to purchase a device and expect it to last forever, but at around $170, I DO expect it to last for longer than a year. Around this time, I noticed that Phillips released a newer version of the brush with smart features and presumed that perhaps they worked out some of the bugs. Apprehensively, I opted to purchase this new model rather than go through Phillips for another replacement of the same apparent dud. I purchased this smart edition (9300 series) on January 31, 2018. Today it is August 15, 2018 and I already began having the exact same issue with this unit about a week ago. Once again, I contacted Phillips to have it replaced and was told that I would need to send the unit in prior to receiving a replacement. I will use this replacement, whenever I actually receive it, until it inevitably ceases to function, but I will never purchase another product from Phillips. Between the terrible quality of their products, and the fact that they make you send in the malfunctioning devices prior to receiving replacement, it is very frustrating. These units still function as ordinary toothbrushes when they aren't turned on. I shouldn't have to go out and purchase a replacement brush while waiting on a replacement, especially after having spent almost $400 in less than 3 years' time. Unbelievable.
