Do Snake Repellers Work

By blogger on

The burning question most people have is. Do snake repellers work?
There are many people who will post that they don’t work, some say they do and youtube has a lot of posts about the pro’s and con’s. The thing I have noticed is that most of the derogatory comments seem to come from snake catchers.
So the only thing to do is to find out as much as possible about these things.

In house test.
The best thing to do is to try it. So when I found a snake in the front garden, I placed one of these electronic snake repellers in the middle of the garden which was about 6 metres across.

The snake was living in a rotted tree stump in the middle of the garden bed.

To make this as close to a test environment as possible, I observed the snakes movements over a 7 day period and would see it out sunbathing and hunting for food. It was a red bellied black snake.

On the afternoon of the 8th day I placed the Sentinel Solar snake repeller in the garden.
The next morning when I went to see the snake sunbathing in its usual spot there was no snake. I checked at the other times when I had seen the snake and sure enough, No Snake.

In this case there seems to be evidence that the snake has been repelled from the area and deterred from returning.
Interestingly, some 6 months later I saw a snake very similar to the other one in another part of the yard about 20 metres from where it was sighted last time. So far I haven’t been able to determine whether or not it’s living permanently in this area.

Other examples of people having success with snake repellers are, this one from the permaculture living forum

Mcintosh Electronics – An Unbiased Mcintosh Review About How They Suck

By blogger on

McIntosh Electronics especially amps in my opinion are of the highest quality electronics known To man! In this review I will go over a little bit of history and review some of the benefits of the products as well as some downfalls. I am her to warn you that I am a bit biased as you can tell from my opening comment, however I will not hesitate to mention the downfalls of the mighty McIntosh electronics in this brief history and product review. So enough with the hubbub and here is my McIntosh review.

McIntosh electronics is known for high quality sound ever since the beginning in 1949. These electronics have been a product that is synonymous with quality and sound production like no other product on the market. Yes they has been in the business for a very long time. And yes just about everyone knows precisely who they are. Many people believed that their quality would diminish after Clarion purchased them, however this is not what happened at all. It makes sense if you think about it – why should any company in their right minds such as Clarion shell out millions of dollars just to purchase another company with a very distinguished name like McIntosh electronics just to throw it down the tubes? Of course this would never happen. Through out McIntosh history they are still making some of the best amplifiers in the world.

Now for the dreaded downfalls of the McIntosh Electronics…Oh No!! As far as this little review goes, there is none..Ha, Ha. Just kidding. Just wanted you to get a little history and now that you understand a little bit about the McIntosh history and benefits lets look into the downfalls just a bit.

When I purchased my first amp. I have to admit that it was very disappointing. With the price that I paid I was expecting to be blown away. It seemed that my speakers just started to shake more, and the clarity of the music out the window with the troublesome bass. I was almost embarrassed to show it off to my friends but I had to…Good thing I did because my buddy said, “Dude your stereo sucks!” I was furious until he went on to explain that my cheap pioneer gear was just not the quality of equipment to carry my new Amp. So reluctantly I put the old equipment back together and waited very impatiently until I could afford some better quality gear. Long story short I eventually put a proper system together and the rest they say is history. I have listened to many different systems and to me there is none better.

So in this little McIntosh review that I have drummed up I will tell you that if you want a better product you are not going to get it, however you must realize that quality gear does not like to work well with cheap stuff that can not handle the power.

For the gifted few who truly expect to have nothing but the best, there is absolutely no substitute. If you are one of the proud who expects nothing but the best sounds without distortion, and absolutely complete control of the output of sound, then there truly is no other choice. This is all that I have to say about wily McIntosh history that is presented in this little McIntosh review.
