I've had the Red Tomato 60L oven for 4 years, but after about 2.5 years of frequent use, the spring in the door broke and we now have to use magnets to keep the door shut. Friends who have the same oven have the same problem, but have rigged up a hook to hold it shut. The oven door frequently falls open, but thankfully the glass doesn't break when it bangs against the cabinet the oven is on.
I wish there was an oven that was comparable in size to the Red Tomato, but none are large enough to fit the cookie sheets and pizza stone we purchased for this oven.
