Owesome color and fast shipping . 1/21/2016
Reviewed by: Fredy from Miami.
Alot of FPV Drone makers are looking to make them drones and build stand out. Great way to give it color. The only complain is that they used to have 1 feet option. Now I need to buy 5 feet minimum. Other than that great product but if you keep making your client buy more than required... what's the point. I find with 1 feet. Bring it BACK !!! hahaha
Colour coding audio cables 11/24/2015
Reviewed by: Peter Barkham from West Vancouver, B.C. Canada.
Used this tubing to colour code microphone cables. Ideal for the job, thin walled. Note that the dimension listed is the internal diameter before shrinking, not the flat dimension.

We were happy with the results with this product. The delivery was good also, the product came on a roll so there was very little wasted product in comparison with some of the tubing we received from other vendors.

Reviewed by: walt from reading, pa.
hi, i know the heat shrink tubing is for electrical wire and those sorts of applications. i use it for arts and crafts kind of stuff. it makes a nice waterproof shrink wrap. the sizes advertised are what you recieve, the turn around time is very good. the clear tubing is very clear and works well for what i need. i ordered realatively small amounts, and got exactly what i ordered at a fair price and quick delivery. i ordered 3 times so far, and would use these folks again. very happy so far

....until I received my heat shrink tubing order. This tubing is GREAT!!! Used it to cover a RG6 cable that ran across a base board, to blend the color into the wall. I expected cheap quality, but this stuff is great. Great that this company sells in small quantities too. I will definitely recommend and will be ordering from here again. Bass Elite
