I choose this keyboard primarily because I have be use IBM\/Lenovo laptop for over 10 year , and the spring mechanism of this keyboard have a tactile feel very similar to these laptop . however , the similarity stop here . Lenovo keyboard be spill-resistant -lrb- some even have a fluid drain -rrb- , and be very easy to maintain . if any drink fall on the keyboard -lrb- which be unavoidable -rrb- , it be easy to remove the key and clean the spring , or even replace the mechanical key subsystem . in the case of this keyboard , by explicit admission of Logitech 's written support , it be very hard to remove key . should one key get slightly damage , replacement key be not available . as it happen , I do imperceptible damange one of the key and make the keyboard unusable . for $ 100 -lrb- a premium price for a commodity product -rrb- , I would expect a more maintainable product . overall , very disappointed . I will not probably buy more Logitech keyboard in the future .
