Query: Expensive, breaks, limited support

Other logitech products I own perform well. This one does not.Maybe i am living in la la land, but when i pay a premium price for a product I expect it to work well for a long period of time. If it stops working, I expect support from the manufacturer to make it right. support of computer equipment should be online and by phone.PROS:feels great, looks great.CONS:after several months of normal use, things began to fall apart, the keyboard began to:lose connection with the computer through BT, requiring a on/off of the BT and reconnectno support to speak of - no driver updates, no forum support, even though there are hundreds of complaints. in fact the moderators simply ignore the requests for assistance - google it.buttons pop off (and are a nightmare to put back)charger stopped working (now it just flashes red/green when in the dock and does not charge).now the only use i see for it is as a frisbee to toss around logitech's headquarters.
