Not anymore, I get totLLY CRIPPLED IF THEY PUT ONE OF THOSE IN MY HEAD, nOW I''M BACK TO A FIXED PRESSURE SHUNT AND THE DAMN DOCTOR PUT THE WRONG ONE IN SO i'M SO WEAK ON MY LEFT SIDE i HAVE TO USE A WALKER AND i'M FALLING ALL OVER THE PLACE. PROGRAMMABLE SHUNTS ONLY LAST ABOUT 8 TO 10 YEARS IF YOUR LUCKY. STICK WITH THE FIXED PRESSURE ONES AND YOU'LL HAVE FAR LESS COMPLICATIONS........
