As a busy dad, I worked hard and tested it in a week at Uber. MPG increased from ~ 40 mpg to about 54 mpg. All I can say is that it

I tested it and got a ~ 20% higher MPG. I wanted more, but it's not bad

I really don't typically leave reviews, but I do when products exceed my expectations and this product is excellent! I was extremely skeptical but this will save me a lot of money, great mpg improvment.

Received in good shape and it works. Nothing to complain about, awesome find!

Very cool invention! however, I believe that this technology should be made public and offered for free! I only paid $28 and not more so I'm glad. It's worth it.

After buying the first one last month for my truck, I took another one for my gasoline car. worked great for me

got a 15% higher gas mileage on a 3.2 v6 with this. Not Bad, thanks a lot Thetechdose!

These clamps are just what I needed! I build bee boxes, cabinets and alot of drawers. They are great! They hold just tight enough so you can adjust the wood in the clamps. I have a few different clamps but these are very simple to use. The max wood size that will fit is about ⅞ but I would not go over ¾. They are also nice for just squaring up boxes because they hold tight as you can hold a square and nail gun. They are a great 3rd hand. I would definitely recommend giving them a try.

Great product. The spring is strong and the quality is good. Support was really nice to me, the whole experience was amazing. I'll order from TheTechDose again.

It came quickly! The clamps themselves are tight enough. In the kit there are three more sets of corners under a sharp and blunt angle. On the base of the clamp there is a line that shows the center of the angle which is pretty useful. All the items are tightly seated in the box. Happy with the purchase.

Excellent corner clamps, wood size that will fit is about ⅞ but I would not go over ¾. They are also nice for just squaring up boxes because they hold tight as you can hold a square and nail gun. They are a great 3rd hand. I would definitely recommend giving them a try.

My father will love them. It's the best gift idea I ever had, for him

These definitely make my life easier. I had been trying to get by with various jury rigs but i caved and got these corner clamps and i don’t regret it. The nicest thing about these ones in particular are that they are spring loaded so you can clamp with one hand rather than needing to tighten with one hand and hold with the other.

Compact. Strong. Heavy duty spring. Easy to use. Works for several sizes of wood, It's definetely a great purchase
