The product was fine but the communication and process of purchasing was an absolute nightmare !
No call backs....no help...couldn't even find out if order had gone through.....will not use again and will not refer to others !
Horrific !
I’ve been loving this pine oil for over 20 years. My recent package arrived leaking, half the bottle gone, and not its usual scent that I love. It kind of smells like stale cigarettes. I’m extremely sad because I’ve wasted a lot of money and plus this is a favorite cleaner.
I have been using this product SBS 40 for over 30 years and it has been a very good product, being medicated it helps my dry skin a lot.
However when I received these 12 tubes from your company I noticed the ingredients list on the back of them are different from the tubes I've been using all these years so I went to back to the site and looked the pictures from the site and the ingredients listed there are the original listed ingredients.
In other words the tubes that I received from you have a list of slightly different ingredients on the tube then what is shown on your website. I'm sure it's a new formula from SC Johnson, which in my opinion is not as good as the original. It has a stronger fragrant and it's thinner but it works ok.
So my point is that your website ingredients listing on the photos should be updated to the current formula.
Thank you.
