My reviews are 100% true, honest and balanced. I do not review products or services that I have not used or had experience with. No product can ever be all bad (or all good), so even if there are negative aspects to the product, I will also discuss and highlight the positives. I always refuse offers that insist on a positive review, not allowing me that discretion.
For sponsored posts, I will have received some form of consideration, whether free product, cash, etc. The guarantees above apply here as well.
