Here is my experience. this device has worked well for 4 months, then start trouble. the cover locks no longer (the small tabs became detached with use) so device not in use. Darty service that offers me to buy a new product !! reasons: 1) it can not find the fault because it does not have cover. 2) Accessories are not sold separate from the device, so you can not only buy the Accessor. 3) Accessories are not included in the warranty. I thought hallucinate !!!! So FLEE
