Of all of the features, the Buffer calender stands out for me, to be able to visually see what tweets and Facebook updates are going out each day of the week is a great tool.
Also, there support is spot on.
On the very occasion I have had to ask a question, their support has been very attentive. Not problem in recommending them! I hope others take a leaf out of Buffers !
The only bugbear (and its a small one) - any links we put on say Buffer to go via Twitter get converted to show them as Buffer links, I guess this is there for reporting but sometimes I would like to see just good old plain URLS of our site in tweets, not Buffers shortened URLS.
By all means look at the competition, but I have used Buffer for many years now. If you are unsure just jump in with the free account and upgrade from there - just do it - its great!
Great time saver, to be able to pre-stack a load of scheduled social media updates to go out at set times means we can then focus on other areas of our marketing.
Even adding images to our scheduled tweets is very easy!
