3D printed parts are of low finish. Lot.of sharp edges on parts. Also the fitment of the parts are not happening because of excess material. Most often the parts have to be filed or reworked. Screws are given in exact number as needed. If one screw is missed, then the assembly is impossible
The consignment was not dispatched as per committed date and had to pursue for dispatch information. The courier didn,t deliver us despit lying in Jaipur and we had to personally collect it from Courier Hub adding to inconvenience. The logistics need to be improved. Just a feedback.
Bought this from this website, stopped working within a month. Support made me wait for weeks, slow response.
At the end the Abhiram from the technical team tells me I should take it to some local electrical repair person who might be able to change the element.
Disgusting quality and service. I was told it does come under warranty but still no solution.
I've sent them photos, videos, nothing. Disgusting service.
