Hello guys this is Akash from Nagpur today I am going to share my views on this inverter named Su kam bryony Eco 1100 wave sign inverter as I told in the title it is not an efficient product for you it will make you feel that buying this is your bad decision I bought this product near about 5 months ago for my home use during the use of 2 to 3 months it gives satisfactory performance but after that I started to face number of problems in it such as its battery draining rate is becomes too fast unless it needs not charging and it also take large amount of electricity to get charged and the time required for charging is also mo Sam suggesting you all to spend some more and go with best thank you
