I bought 4 syska led bulbs last month. I have been using this for 1 month. And I feel my home brighter in night.and it is easy to use .we can put this bulb in the holder as we Put other bulb and it is very easy.and the company provides 1 year gurantee with this also. And the style and design of these bulbs is very attractive and nice.i was using some chinese company’s bulb before syska led bulbs but they were not giving sufficient light. That is why I changed those bulbs with syska led bulbs. And I am very happy with the perfomance of these bulbs. I must say this product is very good value for money.service of this product is very awesome.
