Robus Electronic Transformer 35-105VA is rated 4.4 out of 5 by 32.
Rated 1 out of 5 by from Failed after 14 months. Bought to replace a failed 15year old low voltage down lighter transformer. Chose this make, as opposed to the cheaper Halolight make, as could wire in to existing wiring leads without having to make any junctions/connections. Worked fine, but after 14 months (2 months out of warranty) it stopped. Took apart to find out why it failed, and found it had failed due to a burnt out resistor. The resistor was burnt out due to being stuck under some double sided foam tape used to secure the internal PCB in the case. This is very very very poor design, clearly insulating the resistor allowed it to over heat and burn out. Replaced with cheaper Halolight electronic transformer (and associated chocolate block connector). These have 3 year warranty. Only 1 star for reliability.

Rated 4 out of 5 by from Down light transformer Cheap and easy to fit. I agree about the blue mains input cover is a bit stubborn to remove.

Rated 4 out of 5 by from From Halogen to LED Changed from 5 x 25W Halogen to 5 x 5W LED's. Old dimable Halogen transformer broke down ( got flickering lights) so need to change. I bought 3 LED based Transformers non of which worked as they did not have 25W output, but although this one has 35VA to 105VA its seems to work. I think VA = WATT, but for some rason it works for 25W when it seems the minimum "may" be 35W3 (assuming 35VA = 35W ) - WHY DONT THEY GIVE SOME DECENT ADVICE ????
