Okay, I admit it, I was looking for a bargain, so I bought a fairly cheap product from Lutal to help me with Powerpoint Presentations at work. When it arrived I had no concerns. Big change after half a dozen uses though! It completely fell apart on me. The laser pointer was not working and I unscrewed the barrel to check the batteries. At that, the three function buttons fell out and the appeared to be simply stuck to a piece of masking tape. try as I might I could not reassemble the damn thing and it refused to work.
As it was only used a few times and only a few months old, I wrote to Lutall three times for a replacement or refund. yes, you know what's coming next...they have completely blanked me and Amazon don't want to know because its beyond 60 days post delivery date. So, I have a supplier who couldn't care less about the shabby goods they supply and Amazon who are hiding behind their 60 day rule. AVOID THIS PRODUCT AND THIS SUPPLIER AT ALL COSTS!!!
