After several weeks, majority of blocks were uneaten, and two of the blocks actually had rat droppings on them, as if the rats were "poo-pooing" the bait. I have resorted to traps with various baits in order to deep the little buggers in check.

It's just a block of die-cut "pluck-and-pick" foam. It's rated 3-Stars, because the cutting is not uniform. Some blocks fall apart, others are difficult to rip out.

I used my hot glue gun to reinforce the fall-apart sections. It worked.

I purchased the 500 package.  I'd like to note right off that it came in a sealed bag that was inspected by Amazon.  I was missing 44 blocks, but I believe that this was an issue with the Amazon Warehouse and not the seller.  I have resolved this issue with Amazon.

Out of the blocks that I received, the majority of them were consistent in size and shape and nicely sanded.  There were a few that had a stray piece of wood that was easily removed and didn't have a negative impact on the block.  I could only see 5 that were defective (2 with corners chopped off, 1 that was cut too short, 1 cut at an angle on one face, and 1 with a rough edge).  All things considered, 1% defective parts was not a bad deal.

From an EMail from my father sent, which included photos of ash buildup:
One of the advertised advantages of the Intrepid II metal catalyst block over the ceramic one was that the sharp edges did not provide space for ash build-up and that one need only clean the catalyst about once a year. Not having to disassemble the stove every couple of weeks was appealing to me.

I thought that I would examine the catalyst block after a month or so of operation, just to make sure. In less than a month, the stove was not functioning very well, so I took a peek last night. I knocked a little of the ash off getting it out, but this is the most plugged I have ever seen a catalyst block.

So, I am re-instituting the practice of bi-weekly catalyst cleaning.

These blocks are gorgeous and I love that they're made in the USA. I am disappointed that I've only had them a few days and at least half of them are already splintering...I guess I'll be sanding down blocks this weekend.

The area at the bottom of the rim didn't raise up that way, it was taking different shape, something steady would help.

When I first used this on my lawn (bermuda grass), it seemed to work really well.  Killed a lot of the weeds, but not all of them, which was fine.  However, after only a few weeks, the weeds started coming back.  It worked better on my front lawn which is slightly sloped, but it didn't work so well on my backyard.  The good part is that there is plenty in there to spray the front and back several times.

Initially all of the cords worked, but after a couple of weeks they started to quit working one by one. I think we still have one that is functioning.

The soil blocks require a lot of pressure and manual effort (using fingers to push directly into the underside of block) to compress the soil enough for a firm block.  This may be attributed to the poor quality of the soil block mix. The mix has mulch and rocks the size of dimes, as well as a high percentage of smaller chunks. This makes compaction very difficult. I will try soil blocks with a finer mix and see if this alleviates the problem with poor block formation.

Many of the larger stones had fallen out of their setting.  Hopefully I won't loose any stones during the event

Bolts were severely bent on the threaded end. Check the bolts by rolling the bolts on a flat surface make sure they're straight. If tightened these bolts would have stripped the threads in my block.

I have had this unit for almost 3 years and it has served me well. It has 1 limitation, however, that became evident in the last 6 months, in that it can block only 30 numbers. Old blocks can be deleted so new can be added. But if you expect to have 30 plus active blocks, then you need a unit with greater block capacity.

I had been using a v block stop. Sometimes it would roll over and present a problem. This eliminated the problem..

These blocks were very helpful to me.  I was under the mistaken assumption that Melissa and Doug was a high quality toy company, and these blocks cleared that right up.  The company produces the same crappy, low quality, made-in-China toys that you can get at dollar stores for a fraction the price, they just have the right combination of marketing and packaging to hoodwink people into thinking their wares are decent.

The blocks weren't great to start with.  The paint was smudged on many of them, but the real stunner was that the blocks were in many cases poorly cut and not sanded/finished properly.  This meant lots of rough, splintery edges.  The paint also comes off really easily, even just from scratching.  Might as well let your kid play with scrap wood from a construction site.

Don't be fooled.  If you want high quality blocks, order from one of the many companies out there that offer legitimately good ones.  Otherwise buy a cheap off-brand and save a lot compared to the swindlers at Doug and Melissa.

A few of the punch down points refused to hold onto the wire so we have some unused ports because of that.  Overall I had about 5 fail which took away all the backup spaces I had planned for.

I really wanted to be able to give this item a high review, because I really wanted it to be great!  Unfortunately, we didn't have great luck with these blocks.  They worked well for about an hour, then didn't work very well.  I changed the batteries, took it apart, and finally got it to work again, though I feared breathing on it might stop it again.  It's hard to rate something like this.  I give it high grades when it's working, and low grades when it's not.  Hence, the middle of the road review.

After a few weeks of printing fairly okay quality, my print  heads were clogged, and pages were coming out all yellow or all pink.  Then the printer wouldn't print anything legible.  That was AFTER cleaning my print heads.  Not worth the gamble.
