I bought this OTG around 2yrs back. I didnt really do a survey, but expecting a good product from a good company , I bought it rather in a hurry ( on after throught).
There were problems with the product. First, the light would go off within a few minutes of turning the OTG on. So I would have to open the front cover to check the food.
Next, the shelves didnt fit in properly into the slots - they would fall off on one side - same with the rotosserie(excuse the spelling if its wrong) - is difficult to fit it and then take it out.
Otherwise, the functions are pretty good with sufficient temperature settings and modes and it performs as expected. The heating function is all ok.
So, my case could have been a rare occurrence, but I would advise anyone who wants to buy this product to thoroughly test it before buying it.
