It looks nice, and the housing is sturdy, but the housing is too big for the bristle heads. They do not extend out enough beyond the housing to REALLY clean your grill grates deeply.

Just put it in the bar sink and I can already just pull out the bristles... This is low quality and would recommend a different brand ... The bristles are sparse and it not much of a "brush".

This Is not The best of Grills. THE PLATES ON THE GRILL IS NOT OF A SKILLET MATERIAL. Therefore, it Doesn't cook nor does the food taste the same. Also, the space is very limited!

I would not recommend this product at all. It is cheaply made and the cover wobbles. I knew it would be small before I ordered it, but it is way too small for even a steak. I like to put onions and green pepper on the grill also to cook at the same time, and there is no room. There is no temperature gauge on this; you just plug it in and it cooks. It also is not even on cooking and you have to continuously turn it. All I want is a product that works well and this is not it. Is there one that works?

While this toothbrush does what it is supposed to do and the 2-minute timer is a nice addition, the design is flawed. It is impossible to brush your teeth with this brush without drooling all over the place. I believe it has to do with the width of the brush attachment. Brushing your teeth with this toothbrush is quite messy, no matter how hard I try, and I would not buy this item again.

I thought this design would be more effective with scraping the drippings in between the grids/grates, but such was not the case. I need t get another brush to adequately clean the grill.

Used this because it was recommended by Weber. This brush is a horrible design. bristles bend easily and because its a handle attached to thin metal it is very flimsy so you don't get and pressure to the grates when cleaning. Another user said he had to clean again after using this brush using his old brush. i had to do the same thing. $5 steel brush at publix worked better than this. poor design

The bristles easily fall out of the brush and it gets clogged very quickly. When I try to unclog it, tons of bristles come out.

Nothing to rave about. it's a brush. The edges seem to work better on the Q120 than the flat part of the brush.
The brush seems to just glide over the grill and not really scrape off the "crusted food".
Go for more a the scrubby kind, where you can apply better pressure and be able to get between cracks.

I like to keep all my grill tools on the grill. I don't bring them in the house they stay with the grill. That being said this brush lacks a strap to hang it from one of the grill hooks. To solve this problem I used a sheet metal drill and drilled a hole thru it. Only to discover that the tool is hollow and filled with sand. When you pick this brush up it feels heavy like it has some serious quality to it. Unfortunately, its really just two pieces of aluminum welded together and filled with sand to give it its weight. Its not necessarily a negative just more of a shock. Also it prevented me from being able to tie a piece of leather to it, thru the hole because the sand just leaked out everytime I moved it. So I ended up using a little bit of duct tape to seal the hole. All in all its a nice purchase but if you want a strap, get a different brush.

Grill brushes do not hold up to the normal cleaning of cast iron grates on my weber grill. The material began to separate and tear away from the product after just a couple of uses. I would not recommend this product to anyone at this time.

The bristles rusted and broke off after only one year.  This happened in spite of keeping the brush under a cover whenever the grill was not in use.

Impossible to keep clean if you grill on a consistent basis. Build quality isn't the best either--the screws often need re-tightening.

I'm not thrilled with this grill, primary because of its design. It's really hard to work with if you're trying to do anything more than grill a couple of steaks or hamburgers. The opening is too small and you cannot adjust the height of the grates. On the plus side, charcoal seems to heat up really fast - I think I use less charcoal and everything seems to cook faster too.  But, given the way I use a grill, this probably was not a good choice for me--I cook a lot of roasts and veggies on the grill and this just isn't very good for that kind of cooking.

Extremely difficult to clean even if you are ok with food stuck on it for the next grilling.  Soaking for hours is a must and even then you will need to scrub with a brush. Big mess in the kitchen too.  I shy away from using it for that reason alone.

I purchased this grill brush to replace the Steven Raichlen Grill Brush, which I've thought is the best brush out there except that it's made of wood and always falls apart after a while.  I've owned two of the Steven Raichlen brushes but am tired of them falling apart.  Well, this new BBQ Grill Brush has a good handle and with its design I doubt it will fall apart on me.  That's good.  You can hose it down to clean it off easily.  However, the brass bristles are rather short, in my opinion not very dense and almost half the bristles on this brush (due to the design) will never even see the grill surface.  I've used the brush twice so far.  It cleans the grill surface will a little effort but no better than any other short bristled inexpensive brush.  The long handle is nice though if that's what you're looking for.  I likely won't be buying this again when it wears out.

UPDATE:  I've used the brush a number of times now.  I'm not sure the bristles will last very long.  The handle and wire brush head frame will likely last a long time.  It's a shame the bristles aren't longer and more densely packed on the brush.

UPDATE 2:  As I thought, the bristles wore out quickly and started falling off.  I grill a couple of times per week. and the bristles only lasted 3 months.

looks like playing pickup sticks in my pool, bristles coming out by the dozens after a couple weeks. My previous brush lasted 3 years.

Too late to return this one.
