So at times to be honest, this unit is great fun. My girlfriend and I can not understand the bad reviews. OK all right the remote control is not necessarily the best, but I expect yes also no phone reception in a cave or? The build quality is high, the material feels soft to adhere to without, the design does not look shabby, the charging station is more like an external hard drive -So no stress are at the table to the things lassen- times and sitting my friend describes as very pleasant -bleibt also usually there where he should stay. The range problem with the remote control can be solved simply by going closer to the device, cavers will therefore have no problem with that. So if you want to experience something with his partner is well advised with this thing because it is for both something. We can only say: "Best investment in a long time" The successor must but liked even more programs and steps have said yes individual needs are and are not available on the product itself. Addictive !!!!
