Works, but needed modification

It's no surprise that this is a knock off item. As such, beware that the housing my not fit in your projector so hang on to your original housing. I installed this in a BenQ 1085ST. This bulb is physically smaller in diameter than the OSRAM original and therefore, does not fit in the original housing. The housing that it came with was too short and either the bulb didn't light up with the prism and sit flush, or the plug wouldn't line up. So I basically had to take the bulb housing off of each and swap them so that everything would fit.

It's only been in use for a couple of days, so I can't speak to bulb life, but so far so good. I haven't heard any complaints from my customer. If the bulbs last for a good while, and now that I have a working housing, I'd be happy to buy these again. I will update down the line to speak to bulb quality/life.

Had to modify to make it work where I wanted it installed.  Cord was too short and materials used are cheap.

Junk instructions, poor design, had to make it fit

Worked well, but some modification is required if running a 6 1/2" round speaker, but very minor.  the 5 tabs (3 small, 2 big), on the inside of the circle need to be removed.

I had to modify the dyier wiring to make it work.  But the part did what it should

Needed small adjustments, but overall works amazing!

Had to do a lot of modification for it to fit and work correctly. One of the tracks are fixed and that created a lot of problems .

Not bad. Some of the connectors didn't fit, so had to make that work.

Works well although it was tough to get the right fit.

Difficult  to install, but it works and looks good.

Had to slightly modify to get it to fit my application.  Maybe I should have paid more attention to the description and the bracket shown.

Took some work to install on my kid's 16 inch Avigo Bike (Toys R Us). Had to use a truckload of zip ties. I also had to cut the end off a bit since it was too long, but overall I was able to make it work with some effort. I'll try to upload some photos later on.

Serves its purpose, but does require adjustment after use.

since this as a generic one size fits all kind of fan, I had to make some modifications to it to make it work.  It's a little noisy because of my modifications, but it's in a spare fridge in the basement, so I'm not terribly concerned by it. Also at a third of the price of the OEM part, it was worth spending a half hour modifying the part to fit and work

Works fine after some modifications to the heater hose.

needed some work, but got it reworked and its a viable product

Some modification helped-- I cut off the 1" or so of the wood that extended beyond the bristles, which helped. Plastic scraper portion not particularly robust, but that wasn't a huge issue for me.
