I have been using this product for a long time and I have to say that it is great. No complaints with it.

My problem lies with the delivery service uses - namely UPS. When my wife got home she noticed that the box was leaking everywhere since it was LEFT ON ITS SIDE when the label on the box said THIS SIDE UP. So here we are with leaking bottles of additive inside and outside of the box. Also left a really strong smell that made me feel sick when unpacking the box. Not what I envisioned when ordering this product. please use a more professional delivery service. After ordering this product from you over the past three years I am considering switching to a different vendor.

Bye Bye Stanadyne

After testing the LubriGuard against Stanadyne the results with UltraGuard are similar. 2 to 4% better results with UltraGuard vs Stanadyne and at a lower cost per treatment. Will be full on with the Alliant products now.
