I used it constantly for a good two years. The tape was always out of order, and I remember I blew up around 3 or 4 tape recorders with it, and my parents were not too happy of my using of the tape recorders and the TV. I clearly remember at one point my father literally kicked the tape recorder out of frustration. There were maybe months in a row I wrote my assembly programs in paper, and poked them on BASIC to try them because I had not a tape recorder in working conditions. By around the 3rd year I bought myself a XT, and maybe a year and something after, or two, a 386SX, and I only picked up the Spectrum maybe one year later on where I experimented with it during summer time to understand better some undocumented instructions for an emulator I was beginning to write in C.
