The Remington ES-1000 was probably the best slot-head shaver ever made by Remington. I cannot believe that the market demand was so low as to prompt a cancellation of production. I believe that the production run was limited to about 4 years or so. I have 8 of these shavers and keep a couple old Remington slot heads around as well. The ES-1000 was not perfect. The batteries were way too small and stressed so battery life was poor.You could not buy individual blades as you could with past Remington slot-head units.Also, the edge of the head was too exposed and sharp and when used for body shaving would tend to cut the skin.Slot-head shavers are superior for body shaving and for skin that is suseptible to shaving bumps.They are also great for young men that are prone to ingrown hairs.My guess is that the Norelco 3 head has taken it's place. Those shavers actually use 3 small slot heads. Rumor has it that shavers.com is trying to have a new slot head manufactured in Asia.
