I considered the Sentinella when I was in Spain.
It has changed name and ownership since then, i believe.
I was warned away by a person who had a series of bad experiences and stories from several owners, i won`t write as I`m sure it`ll result in bad feelin.
I still post links here to the mag as it is a good concept and a great source of info.
But like all franchises, they tend to favour the sellers of the franchise, the few owners and all the readers.
A bit like Betterware, the more people invest, give up, the more betterware franchises get sold, betterware ain`t interested in the products as much, the profit is in the franchise sellin.
No franchise is good if you keep the same investor’s, the trick is too lose them after a period of time, but not too many as you get a bad reputation and then gain new investor’s, unless your MacDonald’s and can expand all over the world first, then dumb on the investor’s.
That’s where a lot of franchise sellers fall, the don`t expand enough and they gain a poor reputation.
