I've had my GF-190 for just over a year now and I'm extremely happy with it. Being a Nabertherm it's extremely well made, very easy to maintain and extremely easy to use. Mine has the 300 controller rather than the new 440 but this too is easy to programme and very clear to read. Luckily for me the gas rams which hold the lid up can be removed and the kiln can be separated into two pieces for transport if you need to. My studio is through a narrow gate and up five steps so this came in very handy when installing it. I have only had one small thing happen and that was that the thermocouple needed to be replaced this month. Thermocouples are a 'wear' item and are not covered by warranty so although the original Nabertherm part is expensive it was a simple plug-n-play replacement. Overall I'm extremely glad I bought the Nabertherm. After being used as my own main kiln and for teaching students for over a year it still looks brand new and shows no signs of it's age at all.
